That’s the terrifying reality of modern website infections. Unlike a broken link or a crashed page, malware often operates silently in the background, stealing data, infecting visitors, and damaging your reputation while everything appears normal on the surface.

Studies show that the average time it takes for a website owner to discover they’ve been hacked is 197 days. That’s over six months of:

  • Visitors getting infected with malware
  • Google penalizing your search rankings
  • Customer data being stolen
  • Your brand reputation eroding
  • Potential legal liability accumulating

But here’s the good news: malware infections leave telltale signs. If you know what to look for, you can catch infections early—potentially saving your business from catastrophic damage.

As website security professionals who clean hundreds of infected sites annually, we’ve compiled the 15 most common warning signs that indicate your website has malware. Some are obvious, others are subtle, but all of them require immediate attention.

If you recognize even one of these symptoms, your website needs immediate investigation.

Warning Sign #1: Google Displays a Security Warning on Your Site

What It Looks Like

Visitors trying to access your website see a full-screen warning:

  • “Deceptive site ahead”
  • “This site may be hacked”
  • “The site ahead contains malware”
  • “Phishing ahead”

The warning appears before visitors can access your content, with a prominent “Back to safety” button.

Why This Happens

Google crawls billions of web pages daily, analyzing them for malicious content. When their automated systems detect malware, phishing pages, or suspicious redirects on your site, they immediately flag it to protect users.

This isn’t a false alarm—Google’s malware detection has a less than 1% false positive rate. If you’re seeing this warning, your site is almost certainly compromised.

What To Check

  1. Visit your site in an incognito window (malware often hides from logged-in users)
  2. Check Google Search Console for security issues
  3. Review your site’s safety status at Google Safe Browsing

The Severity

CRITICAL – Handle Immediately

Every hour this warning displays, you’re losing:

  • 95% of your organic traffic (visitors won’t bypass the warning)
  • Search engine rankings (Google penalizes infected sites)
  • Customer trust (even after cleanup, reputation damage persists)

Typical Revenue Impact: E-commerce sites lose an average of $5,000-$50,000 per day when blacklisted.

What To Do Right Now

  1. Do not ignore this or hope it goes away – It won’t
  2. Contact Google Search Console to understand the specific issue
  3. Immediately scan your entire website with professional malware detection tools
  4. If you lack expertise, contact a security professional within 1 hour

Timeline: Most blacklist removals take 3-7 days even after malware is completely removed. Every day of delay costs you money and reputation.


Warning Sign #2: Your Site Redirects to Strange Websites

What It Looks Like

When someone clicks on your website in search results or types your URL, they’re automatically redirected to:

  • Pharmaceutical sites (Viagra, Cialis)
  • Gambling or casino websites
  • Adult content sites
  • Fake tech support pages
  • Unknown foreign language sites
  • Survey scam pages

Sometimes the redirect only happens:

  • To visitors from search engines (not direct traffic)
  • To users not logged into WordPress
  • On mobile devices only
  • From specific countries
  • At certain times of day

Why This Happens

Attackers inject redirect code into your website to monetize your traffic. They earn money when your visitors land on these sites through:

  • Affiliate commissions
  • Pay-per-click revenue
  • Malware installation bounties
  • Phishing scam conversions

The redirects are often conditional (targeting only certain visitors) to avoid detection by site owners who are usually logged in.

What To Check

  1. Test from multiple devices: Open your site on your phone, laptop, and ask friends to visit
  2. Clear browser cache first: Old cache can hide redirects
  3. Test in incognito/private mode: Malware often won’t redirect logged-in admins
  4. Click from Google search results: Many redirects only trigger from search engines
  5. Check your .htaccess file (if on Apache server) – look for suspicious redirect rules
  6. Examine your header.php and footer.php files – common injection points

The Severity

HIGH – Resolve Within 24 Hours

Consequences:

  • Google will blacklist your site within days
  • Search rankings plummet (may take months to recover)
  • Visitors will never return after being redirected to scam sites
  • Your domain reputation is permanently damaged
  • You could face legal liability if visitors are harmed

What To Do Right Now

  1. Take your site offline temporarily if redirects are severe
  2. Scan all files for base64-encoded code (common obfuscation method)
  3. Search for suspicious JavaScript in your database
  4. Check all theme and plugin files for modifications
  5. Consider professional malware removal if you can’t locate the source

Common Hiding Places:

  • .htaccess file
  • header.php and footer.php
  • wp-config.php
  • Core files that should never be modified
  • Fake plugins with legitimate-sounding names

Warning Sign #3: Strange Pop-Ups or Ads Appear That You Didn’t Add

What It Looks Like

Your website suddenly displays:

  • Aggressive pop-up advertisements
  • Adult or inappropriate ads
  • “You’ve won a prize!” banners
  • Fake virus warnings (“Your computer is infected!”)
  • Unexpected banner ads in unusual locations
  • Pop-unders that open behind the main window
  • Auto-playing video ads
  • Notification permission requests

The ads don’t match your website’s industry or professional image, and you definitely didn’t install any ad networks.

Why This Happens

Attackers inject ad code (often called “adware” or “malvertising”) to profit from your traffic. Every view or click generates revenue for the attacker.

This is one of the most common monetization methods because:

  • It’s harder to detect than outright theft
  • Site owners sometimes think they accidentally installed an ad plugin
  • Visitors might assume the site owner is just aggressive with advertising
  • It can run for months before being noticed

What To Check

  1. View your site when logged out – Ad injection often targets only visitors
  2. Test on different browsers and devices
  3. Check your browser console for loaded scripts from unknown domains
  4. Review recently installed plugins – fake ad plugins are common
  5. Inspect your website’s source code – search for suspicious <script> tags
  6. Look for unauthorized JavaScript in your database wp_posts table

The Severity

MEDIUM-HIGH – Resolve Within 48 Hours

While not as immediately damaging as blacklisting, malicious ads:

  • Destroy user experience and credibility
  • Can install additional malware on visitors’ devices
  • Violate Google’s quality guidelines (ranking penalty)
  • May get you flagged by antivirus software
  • Create legal liability if visitors are harmed
  • Dramatically increase bounce rate

What To Do Right Now

  1. Document what you’re seeing (screenshots, URLs of ads)
  2. Check your Google Analytics for unusual referral sources
  3. Scan for recently modified files
  4. Search your database for suspicious scripts
  5. Review all admin user accounts for unauthorized additions

Red Flag Locations:

  • Injected into wp_options table (WordPress)
  • Added to theme functions.php
  • Hidden in plugin files
  • Encoded in database content

Warning Sign #4: Your Website Performance Suddenly Degrades

What It Looks Like

Your previously fast-loading website now:

  • Takes 10+ seconds to load
  • Times out completely
  • Shows intermittent availability
  • Consumes excessive server resources
  • Experiences unexplained CPU spikes
  • Has unusually high memory usage
  • Generates massive amounts of traffic

Your hosting provider might even suspend your account for “excessive resource usage.”

Why This Happens

Several malware types cause performance degradation:

Cryptocurrency Miners: Code that uses your server’s CPU to mine Bitcoin, Monero, or other cryptocurrencies for attackers Botnet Participation: Your server is part of a network attacking other targets Mass Email Spam: Your server is sending thousands/millions of spam emails Data Exfiltration: Large amounts of data being uploaded to attacker servers Malware Distribution: Your site is hosting and distributing malware files to thousands of infected devices

What To Check

  1. Server resource usage: Check CPU, memory, and bandwidth in your hosting control panel
  2. Process list: Look for unknown processes consuming resources
  3. Network activity: Unusual outbound connections
  4. Error logs: Check for repeated errors or unusual patterns
  5. Database queries: Slow queries that didn’t exist before
  6. Cron jobs: Unauthorized scheduled tasks

The Severity

MEDIUM – Investigate Within 24 Hours

Immediate impacts:

  • Poor user experience (visitors leave)
  • Higher bounce rate (SEO penalty)
  • Potential hosting account suspension
  • Increased hosting costs
  • Server crash risk
  • Your server attacking others (legal liability)

What To Do Right Now

  1. Check your hosting control panel for resource usage graphs
  2. Review process lists for unfamiliar processes
  3. Check outbound network connections
  4. Examine cron jobs for unauthorized tasks
  5. Review email logs (if available) for spam activity
  6. Run malware scan focusing on:
    • Hidden cryptocurrency mining scripts
    • Spam relay code
    • Botnet participation scripts

Hosting providers often detect this first and will email you about “excessive resource usage” or “terms of service violation.”


Warning Sign #5: Unexpected Spam Emails Come From Your Domain

What It Looks Like

You or your customers start receiving:

  • Spam emails that appear to come from your domain
  • Bounce-back messages for emails you never sent
  • Complaints from recipients about spam from your addresses
  • Blacklist notifications from email providers
  • Your legitimate emails going to spam folders
  • Hundreds or thousands of “undelivered mail” notices

Why This Happens

Attackers compromise your website and use it to:

  • Send spam emails using your mail server
  • Forge your domain in email headers (if SPF/DKIM not configured)
  • Access contact forms to send spam
  • Harvest email addresses from your database
  • Use your server as a spam relay

Your domain gets flagged by spam blacklists (Spamhaus, SpamCop, SORBS), destroying your email deliverability.

What To Check

  1. Check if you’re blacklisted: Use MXToolbox Blacklist Check
  2. Review mail logs: Look for unusual sending patterns
  3. Check email queue: Thousands of queued messages indicate spam relay
  4. Verify SPF, DKIM, and DMARC records: Properly configured email authentication
  5. Review contact form submissions: Spam bots often exploit forms
  6. Check for email scripts: Look for unauthorized PHP mail scripts

The Severity

HIGH – Address Within 24 Hours

Consequences:

  • Your legitimate emails won’t reach customers
  • Business communication breaks down
  • Email accounts may be suspended by provider
  • Domain reputation permanently damaged
  • Removal from blacklists takes weeks or months
  • Potential CAN-SPAM Act violations (legal issues)

What To Do Right Now

  1. Change all email account passwords immediately
  2. Enable two-factor authentication on email accounts
  3. Check server for unauthorized PHP mail scripts
  4. Review and secure all contact forms
  5. Scan for compromised email accounts
  6. Contact your email provider about the issue
  7. Submit delisting requests to blacklist operators (after cleanup)

Prevention: Implement SPF, DKIM, and DMARC authentication to prevent email spoofing.


Warning Sign #6: Unknown User Accounts Appear in Your Admin Panel

What It Looks Like

When checking your WordPress admin panel (or other CMS), you discover:

  • User accounts you didn’t create
  • Accounts with suspicious names (admin2, support, backup, service)
  • Accounts with admin/administrator privileges
  • Recently created accounts with no activity history
  • Accounts with strange email addresses
  • Suspended or hidden accounts that still have access

Why This Happens

After gaining initial access, attackers create backdoor admin accounts to maintain persistent access even if you:

  • Change your password
  • Remove the original malware
  • Update plugins and themes

These accounts are often named to look legitimate: “support,” “backup_admin,” “wordpress_service,” or they use generic names like “user12345.”

What To Check

  1. Review all user accounts: WordPress Users → All Users (check thoroughly)
  2. Sort by registration date: Recent accounts are suspicious
  3. Check user roles: Focus on Administrator and Editor roles
  4. Look for unusual email addresses: Temporary email services, foreign domains
  5. Review account activity: No posts/comments but admin access = red flag
  6. Check your database: wp_users table for additional accounts

The Severity

CRITICAL – Remove Immediately

This is a major security breach because:

  • Attackers have full control of your site
  • They can return anytime even after cleanup
  • They can create additional backdoors
  • They can modify any content or settings
  • They can steal all data in your database
  • They can install malware repeatedly

What To Do Right Now

  1. Do not delete accounts yet – Document them first (username, email, IP address if available)
  2. Change all existing legitimate user passwords immediately
  3. Enable two-factor authentication for all admin accounts
  4. Delete suspicious accounts after documentation
  5. Check logs to see what these accounts accessed
  6. Perform full malware scan (other backdoors likely exist)
  7. Review file modification dates to see what they changed

Critical: Deleting the account isn’t enough. You must find and remove all backdoors they created.


Warning Sign #7: Your Website Content Changes Without Your Knowledge

What It Looks Like

You notice:

  • Pages or posts you didn’t create
  • Existing content modified without your knowledge
  • Hidden links added to your content
  • Text replaced with gibberish or spam
  • Pharmaceutical keywords injected into content
  • Adult content or gambling links added
  • Comment spam published automatically
  • Your homepage completely replaced
  • Defacement (hacker’s message or logo)

Why This Happens

SEO Spam Injection: Attackers inject hidden links to manipulate search rankings for their sites or clients. The links might be:

  • Invisible (white text on white background)
  • Tiny (1px font size)
  • Hidden with CSS (display:none)
  • Shown only to search engines

Defacement: Some attackers want recognition and replace your homepage with their message. This is less common but more obvious.

Content Replacement: Sophisticated attacks replace your valuable content with malware distribution pages or phishing content.

What To Check

  1. View your homepage and key pages while logged out
  2. View source code: Look for hidden links
  3. Check recent post/page modifications: Most CMS platforms track this
  4. Search your site on Google: site:yoursite.com viagra or site:yoursite.com casino
  5. Review post revisions: WordPress keeps revision history
  6. Search database for spam keywords: Search for terms like “viagra,” “casino,” “cialis,” “porn”

The Severity

MEDIUM-HIGH – Investigate Within 24 Hours

Impacts:

  • Google penalties for spam (manual or algorithmic)
  • Ranking loss for legitimate keywords
  • User trust evaporates
  • Brand reputation damage
  • Visitors associate your brand with spam
  • Potential legal issues (adult content, counterfeit goods)

What To Do Right Now

  1. Document all unauthorized changes (screenshots)
  2. Remove obvious spam immediately
  3. Search database for injected content
  4. Check theme files (header.php, footer.php) for hidden link injection
  5. Review all widgets and sidebars
  6. Scan for malware that’s modifying content automatically
  7. Change all passwords and revoke suspicious access

Note: Simply removing visible spam isn’t enough—the malware will just inject it again.


Warning Sign #8: Antivirus Software Warns About Your Website

What It Looks Like

You or your visitors receive warnings from:

  • Norton: “This website is unsafe”
  • McAfee: “This site may harm your computer”
  • Avast: “Threat has been detected”
  • Windows Defender: “This site has been reported as unsafe”
  • Browser warnings: “Dangerous site blocked”

The warnings might mention specific threats like:

  • Trojan.Script.Malicious
  • JS:Malware-gen
  • PHP:Backdoor-A
  • HTML:Iframe-inf

Why This Happens

Antivirus companies continuously scan popular websites. When they detect malware, they add your domain to their threat databases. Every user with that antivirus software will see warnings when visiting your site.

This happens when your site:

  • Distributes malware to visitors
  • Contains exploit code
  • Hosts phishing pages
  • Has drive-by download attacks
  • Links to known malicious domains

What To Check

  1. Test your site at multiple security scanners:
  2. Check your files for: Malicious iframes, suspicious JavaScript, encoded PHP, unknown file uploads
  3. Review external links: Your site might be linking to infected sites

The Severity

CRITICAL – Address Immediately

Once antivirus software flags your site:

  • Instant 70-90% traffic drop
  • Google notices and may blacklist you next
  • Domain reputation severely damaged
  • Recovery takes weeks minimum
  • Business operations effectively stopped
  • Existing customers question your security

What To Do Right Now

  1. Run comprehensive malware scan immediately
  2. Check all file upload directories
  3. Review database for malicious scripts
  4. Examine all external resource links
  5. After cleanup, submit for review to each antivirus company
  6. Monitor daily until warnings are removed

Timeline: Even after complete cleanup, antivirus removal takes 1-4 weeks as each company has different review schedules.


Warning Sign #9: Strange Files Appear on Your Server

What It Looks Like

While browsing your server files via FTP or file manager, you notice:

  • Files with random names: c99.php, r57.php, shell.php, wso.php
  • Files with weird extensions: .suspected, .htpasswd, .ico.php
  • Recently uploaded files you didn’t add
  • Files in unusual locations (root directory, wp-includes, uploads folder)
  • Files with obvious hacker names: backdoor.php, hack.php
  • Image files that are actually PHP scripts
  • Files with suspicious modification dates (recent changes to old files)

Why This Happens

These are backdoors and web shells that give attackers remote access to your server. Common types:

C99 Shell: Full-featured file manager allowing complete server control R57 Shell: Similar backdoor with database access WSO Shell: “Web Shell by Orb” – common and powerful Fake Images: PHP files named like images (logo.png.php) Eval-based backdoors: Small files with heavily obfuscated code

What To Check

  1. Sort files by modification date: Recent changes to old core files are suspicious
  2. Look in unusual locations:
    • wp-includes directory (WordPress)
    • uploads folder
    • temp directories
    • Root directory
  3. Search for specific filenames:
    • c99.php, r57.php, wso.php, shell.php
    • Any file with “symlink,” “shell,” “backdoor” in name
  4. Check file permissions: Files with 777 permissions
  5. Examine file sizes: 1-line PHP files with cryptic code

The Severity

CRITICAL – Remove Immediately

Web shells give attackers:

  • Complete control of your website
  • Ability to view/modify/delete any file
  • Access to your database
  • Capability to upload additional malware
  • Means to attack other servers from yours
  • Tool to steal all customer data

What To Do Right Now

  1. Do NOT delete files yet – Document them (name, location, size, date)
  2. Download suspicious files for analysis (safely, in a sandbox)
  3. Check server logs to see when they were accessed
  4. Change ALL passwords (FTP, database, WordPress, hosting)
  5. Enable two-factor authentication everywhere
  6. Perform complete malware scan
  7. Consider restoring from clean backup (if available)

Important: Finding one shell usually means multiple backdoors exist. Professional malware removal is strongly recommended.


Warning Sign #10: Your Website Appears in Search Results for Unrelated Keywords

What It Looks Like

When checking your Google Search Console or doing Google searches, you discover your site appearing for keywords like:

  • “cheap viagra”
  • “online casino”
  • “replica watches”
  • “payday loans”
  • “essay writing service”
  • Adult content terms
  • Pharmaceutical products

You’ve never created content about these topics, yet search engines show your site in results.

Why This Happens

Attackers inject SEO spam in ways only search engines see:

Cloaking: Different content shown to search engines vs. regular visitors Hidden Content: Text hidden with CSS, same-color text, or tiny fonts Spam Pages: Hundreds of auto-generated pages targeting spam keywords Link Farms: Your site becomes part of link networks

The goal is to manipulate search rankings for lucrative spam keywords by hijacking your domain’s authority.

What To Check

  1. Google Search Console: Check Search Analytics for weird keywords
  2. Google site search: site:yoursite.com viagra (try various spam terms)
  3. Google cache: View cached version of pages (shows what Google sees)
  4. View as Googlebot: Use tools to see what search engines see
  5. Check for hidden content: View source code, disable CSS, look for display:none
  6. Review sitemap.xml: Spam pages often added here
  7. Search for doorway pages: URL patterns like /keyword-city-state/

The Severity

HIGH – Resolve Within 48 Hours

Consequences:

  • Google manual action penalty (very hard to recover from)
  • Rankings drop for your legitimate keywords
  • Domain authority permanently damaged
  • Algorithmic penalties (Panda, Penguin)
  • Years of SEO work destroyed
  • Potential permanent ban from search results

What To Do Right Now

  1. Document all spam keywords appearing in Search Console
  2. Find and remove all spam content
  3. Clean your database of injected spam
  4. Submit URL removal requests for spam pages
  5. Request reconsideration in Search Console (after cleanup)
  6. Check for malware that’s automatically generating spam
  7. Review all installed plugins/themes for SEO spam functionality

Recovery Time: After cleanup, expect 2-6 months for full search ranking recovery.


Warning Sign #11: Your Database Size Suddenly Increases Dramatically

What It Looks Like

Checking your hosting panel, you notice:

  • Database size jumped from 50MB to 500MB+ overnight
  • Unexplained storage limit warnings
  • Database backup files are enormous
  • phpMyAdmin shows tables you don’t recognize
  • Existing tables have millions of extra rows

Why This Happens

Attackers use your database to:

  • Store stolen credit cards or personal information
  • Host phishing data for collection
  • Store malware files and payloads
  • Save spam email lists
  • Cache infected website copies
  • Run cryptocurrency mining operations
  • Host illegal content

What To Check

  1. Check database size: Compare to previous backups
  2. Review table sizes: Look for unusually large tables
  3. Check table row counts: Should match expected content
  4. Look for unknown tables: Tables you didn’t create
  5. Examine wp_options or settings tables: Often bloated with spam
  6. Check for base64 encoded data: Sign of hidden malicious content

The Severity

MEDIUM-HIGH – Investigate Within 24 Hours

Issues:

  • Significant hosting cost increases
  • Database performance degradation
  • Backup failures (files too large)
  • Your site becomes slow or unresponsive
  • You’re storing illegal content (legal liability)
  • Data breach potential

What To Do Right Now

  1. Export database and analyze table sizes
  2. Identify suspicious tables or excessive data
  3. Check options/settings tables for injected data
  4. Look for spam in post_meta or user_meta tables
  5. Scan database for base64 encoded malware
  6. Remove malicious data after documentation
  7. Optimize database after cleanup

Warning: Don’t delete tables without understanding what they contain—you could break your site.


Warning Sign #12: Unexpected Outbound Traffic or Strange Server Connections

What It Looks Like

Your server monitoring shows:

  • Unusual outbound connections to foreign IP addresses
  • Connections to known malicious domains
  • Data being transmitted at odd hours
  • Bandwidth usage spikes
  • Connections to IRC servers
  • Encrypted traffic to unusual destinations

Why This Happens

Your compromised server is:

  • Participating in DDoS attacks on other sites
  • Communicating with Command & Control (C&C) servers
  • Exfiltrating stolen data to attacker servers
  • Part of a botnet
  • Scanning the internet for other vulnerable sites
  • Relaying spam or malware

What To Check

  1. Server logs: Review access logs and error logs
  2. Network monitoring: Use tools like netstat to see active connections
  3. Firewall logs: What’s being blocked or allowed
  4. Process list: Unknown processes making network connections
  5. Cron jobs: Scheduled tasks that shouldn’t exist

The Severity

HIGH – Investigate Immediately

Your server attacking others means:

  • Your hosting account will be suspended
  • Legal liability for damages caused
  • Your IP will be blacklisted
  • Reputation destruction
  • Potential law enforcement involvement
  • Hosting provider may terminate service permanently

What To Do Right Now

  1. Document all suspicious connections (IP addresses, ports, timestamps)
  2. Block suspicious outbound connections via firewall
  3. Kill unknown processes
  4. Disable suspicious cron jobs
  5. Perform complete malware scan
  6. Consider taking site offline during investigation
  7. Contact hosting provider to inform them you’re investigating

Warning Sign #13: Your SSL Certificate Shows Security Errors

What It Looks Like

Visitors or you see:

  • “Your connection is not private” errors
  • Certificate warnings in browsers
  • Mixed content warnings
  • Certificate expiration notices (but cert should be valid)
  • Certificate name mismatch errors
  • Certificate issued by wrong authority

Why This Happens

Attackers may:

  • Replace your legitimate SSL certificate
  • Perform man-in-the-middle attacks
  • Set up fake SSL to appear legitimate
  • Intercept encrypted traffic
  • Steal login credentials and payment information

Alternatively, it could indicate server compromise where security settings were modified.

What To Check

  1. Verify certificate details: Click the padlock in browser, check certificate info
  2. Check certificate expiration date
  3. Verify certificate issuer: Should match your CA (Let’s Encrypt, Comodo, etc.)
  4. Check certificate domain: Must exactly match your domain
  5. Review SSL configuration: Weak ciphers or protocols enabled
  6. Check for mixed content: HTTP resources on HTTPS pages

The Severity

HIGH – Address Within 24 Hours

Consequences:

  • Visitors will avoid your site (scary browser warnings)
  • E-commerce transactions impossible
  • Google penalizes sites with SSL errors
  • Payment processors may suspend your account
  • PCI compliance failure (fines up to $100,000/month)
  • Data theft through unencrypted connections

What To Do Right Now

  1. Verify your SSL certificate is legitimate and active
  2. Renew expired certificates immediately
  3. Check for certificate replacement or tampering

  7. Consider re-issuing certificate if compromise suspected

Warning Sign #14: You’re Locked Out of Your Own Admin Panel

What It Looks Like

When trying to log into your WordPress admin (or other CMS):

  • Your password no longer works
  • “Incorrect username or password” despite being correct
  • Your admin account doesn’t exist anymore
  • Login page redirects elsewhere
  • Login page looks different
  • Two-factor authentication suddenly doesn’t work
  • Password reset emails never arrive

Why This Happens

Attackers have:

  • Changed your password
  • Deleted your admin account
  • Modified the login system
  • Created a fake login page
  • Changed your email address
  • Disabled password reset functionality
  • Locked you out while they steal data

This is often the point where website owners realize something is seriously wrong—but by this time, the attackers have had days or weeks of access.

What To Check

  1. Verify you’re on the correct login page: Check URL carefully
  2. Try password reset: If email doesn’t arrive, it’s likely compromised
  3. Check database directly: Access via phpMyAdmin, look at users table
  4. Review email account: Attackers may have changed your email
  5. Check user roles: Your account may be downgraded from admin

The Severity

CRITICAL – Emergency Response Required

Being locked out means:

  • Attackers have full control
  • They’re actively stealing data
  • They may be destroying evidence
  • You can’t stop ongoing damage
  • Every minute matters

What To Do Right Now

Emergency Access Methods:

  1. Database password reset:
    • Access phpMyAdmin
    • Find wp_users table (or equivalent)
    • Update your password hash with new MD5 hash
  2. FTP file upload:
    • Upload emergency.php script to reset password
    • Run script via browser
    • Delete script immediately after
  3. Hosting control panel:
    • Some hosts have “WordPress password reset” tools
  4. Contact hosting support:
    • They can help restore access
  5. Restore from backup:
    • If recent clean backup exists

After regaining access:

  • Change ALL passwords immediately
  • Enable 2FA on all accounts
  • Perform complete malware removal
  • Check all user accounts
  • Review all recent changes

Warning Sign #15: Your Hosting Provider Contacts You About Suspicious Activity

What It Looks Like

You receive email or notifications from your hosting provider mentioning:

  • “Malware detected on your account”
  • “Terms of Service violation”
  • “Excessive resource usage”
  • “Spam originating from your account”
  • “Your account has been suspended”
  • “Security incident notification”
  • “Outbound attack detected”
  • “Your account is under investigation”

Why This Happens

Hosting providers monitor for:

  • Malware distribution
  • Spam relay activity
  • DDoS participation
  • Excessive server resource consumption
  • Attacks on other customers
  • Terms of Service violations
  • Criminal activity

They often detect infections before website owners do because they monitor server-level activity that’s invisible to site owners.

The Severity

CRITICAL – Respond Immediately

Hosting provider notices mean:

  • Infection is severe and actively causing problems
  • Account suspension is imminent or already occurred
  • Other customers may be affected
  • You’re violating your hosting agreement
  • Account termination possible
  • Legal action potential

What To Do Right Now

  1. Respond to hosting provider immediately – Don’t ignore these emails
  2. Request specific details about what was detected
  3. Ask for suspension to be lifted temporarily for investigation
  4. Begin immediate malware removal
  5. Provide timeline for resolution
  6. Keep hosting provider updated on progress
  7. Consider professional emergency malware removal

Important: Hosting providers typically give 24-48 hours to resolve before permanent suspension. Act fast.


What Happens If You Ignore These Warning Signs?

Let’s be brutally honest about what occurs when malware infections go unaddressed:

Week 1: The Silent Phase

  • Malware spreads deeper into your system
  • More backdoors get installed
  • Customer data begins being stolen
  • Search engines start detecting issues

Week 2-4: The Damage Accelerates

  • Google blacklists your site
  • Traffic drops 70-95%
  • Antivirus software flags your domain
  • Revenue plummets
  • Customer complaints increase

Month 2-3: The Crisis Point

  • Search rankings collapse completely
  • Domain reputation permanently damaged
  • Hosting account suspended
  • Legal notices from affected visitors
  • Potential lawsuits from customers
  • Brand reputation destroyed

Month 4-6: The Aftermath

  • Business may not recover
  • Years of SEO work destroyed
  • Customer trust impossible to rebuild
  • Legal costs mounting
  • Potential business closure

The Statistics Are Sobering:

  • 60% of small businesses close within 6 months of a major cyber attack
  • Average cost of a small business data breach: $36,000-$50,000
  • Recovery time for search rankings: 6-18 months minimum
  • Customer loss rate: 65% of customers leave after a security incident

When to Call Professionals (And When DIY Might Work)

You Can Potentially Handle It Yourself If:

  • You have technical expertise in website administration
  • The infection is newly discovered (within 24-48 hours)
  • You have recent clean backups
  • Only one or two warning signs are present
  • Your website is simple (static pages, minimal functionality)
  • You have time to thoroughly investigate and clean

You NEED Professional Help If:

  • Multiple warning signs from this list apply
  • You’ve been infected for weeks or months (unknown duration)
  • You’re seeing Google blacklist warnings
  • You’ve been locked out of admin panel
  • Your hosting provider has contacted you
  • You handle customer payments or sensitive data
  • You lack technical expertise
  • You’ve tried DIY cleanup but infection persists
  • Your business depends on your website being operational

Professional Malware Removal Includes:

  • Complete forensic analysis of how infection occurred
  • Identification and removal of ALL malware (not just visible infections)
  • Backdoor discovery and elimination
  • Database cleaning
  • Google blacklist removal
  • Antivirus delisting
  • Security hardening to prevent reinfection
  • Post-cleanup monitoring
  • Documentation and reporting
  • Guarantee against reinfection

Reality Check: 73% of DIY malware cleanups result in reinfection within 90 days because hidden backdoors weren’t found.

The math is simple: $1,500 in professional cleanup vs. $50,000+ in consequences.

Frequently Asked Questions

Q: Can malware hide from security scanners? A: Yes. Sophisticated malware uses obfuscation, encryption, and polymorphic techniques. This is why multiple scanning tools and human expertise are necessary.

Q: If I restore from backup, am I safe? A: Only if the backup is from before the infection occurred AND you’ve identified how the infection happened. Otherwise, you’ll be reinfected immediately.

Q: Will reinstalling WordPress/my CMS fix it? A: No. Malware often exists in the database, uploads folder, and other locations that survive reinstallation. Attackers also frequently have server-level access.

Q: How long does complete malware removal take? A: Simple infections: 2-4 hours. Complex infections: 24-72 hours. Severe compromises with extensive damage: 3-7 days.

Q: Can I just install a security plugin? A: Security plugins are preventive tools—they’re not effective at removing existing infections. You must clean the infection first, then implement security measures.

Q: How did I get infected if I didn’t do anything? A: Most infections occur through outdated software vulnerabilities, not user actions. If you’re running old plugins or themes, attackers can exploit them automatically.

Conclusion: Your Website Is Infected – Now What?

If you’ve made it this far and recognized any of these 15 warning signs, the truth is clear: your website needs immediate attention.

The good news: Catching infections early—even if “early” feels late—dramatically reduces damage and recovery time. Every day counts, but taking action today is infinitely better than waiting another week.

The bad news: Malware doesn’t get better on its own. It spreads, it deepens, it causes more damage. The cost—financial and reputational—increases exponentially with time.

Your Next Decision

You have three options:

1. Do Nothing (Not Recommended)

The Imperative Need to Keep Your Website Free from Blacklists and Viruses: A Comprehensive Guide https://www.siteguarding.com/security-blog/the-imperative-need-to-keep-your-website-free-from-blacklists-and-viruses-a-comprehensive-guide/ Wed, 24 Apr 2024 10:56:16 +0000 https://blog.siteguarding.com/?p=672 Read More]]> 

In the digital age, maintaining a website that is free from blacklists and viruses is not just an option, but a necessity. This article aims to shed light on the importance of keeping your website clean and secure, focusing on the dangers of harmful content and the benefits of using Website Blacklist Removal services.

The digital landscape is fraught with potential dangers, with cyber threats evolving at an alarming rate. One of the most common issues faced by website owners is the presence of harmful content. This can include pages that attempt to deceive visitors into sharing personal information or downloading software that could potentially harm their systems. Such content not only poses a risk to your visitors but also tarnishes your website’s reputation.

The phrase “This site is unsafe” is a chilling warning that no website owner wants to see. This warning is often displayed by web browsers when they detect potentially harmful content on a website. It is a clear indication that your website has been blacklisted, a situation that can lead to a significant decrease in traffic and a potential loss of business.

Understanding the Consequences of Blacklisting

When a website is blacklisted, it is essentially flagged as unsafe by search engines and web security services. This can happen for a variety of reasons, including the presence of malware, phishing attempts, or spammy content. Once a website is blacklisted, it becomes difficult for users to access it, as their browsers will display warnings about the site’s safety.

The impact of blacklisting can be severe. It can lead to a significant drop in website traffic, as potential visitors are deterred by safety warnings. This can, in turn, lead to a loss of business and revenue. Moreover, being blacklisted can also damage your website’s reputation, making it harder to regain the trust of your visitors even after the issue has been resolved.

The Importance of Keeping Your Website Clean

Keeping your website free from harmful content is crucial for several reasons. Firstly, it ensures the safety of your visitors. By ensuring that your website does not contain any pages that try to trick visitors into sharing personal info or downloading software, you are protecting them from potential harm.

Secondly, maintaining a clean website helps to preserve your website’s reputation. A website that is known for being safe and secure is more likely to attract and retain visitors. On the other hand, a website that is known for containing harmful content is likely to be avoided.

Lastly, keeping your website clean can also help to improve its search engine ranking. Search engines like Google prioritize the safety and security of their users. As such, they are more likely to rank websites that are free from harmful content higher in their search results.

The Role of Website Blacklist Removal Services

Given the potential consequences of blacklisting, it is crucial to address the issue as soon as possible. This is where Website Blacklist Removal services come in. These services are designed to help website owners remove their websites from blacklists and restore their reputation.

Website Blacklist Removal services typically involve a comprehensive scan of your website to identify any harmful content or security vulnerabilities. Once these issues have been identified, the service provider will work to resolve them. This can involve removing harmful content, cleaning up any malware infections, and securing your website to prevent future issues.

Moreover, these services also often include assistance with submitting a review request to search engines and web security services. This is a crucial step in the process, as it can help to expedite the removal of your website from blacklists.

In conclusion, keeping your website free from blacklists and viruses is of paramount importance. It not only ensures the safety of your visitors but also helps to preserve your website’s reputation and improve its search engine ranking. By using Website Blacklist Removal services, you can effectively address any issues and ensure that your website remains safe and secure.

How to stop a mobile redirecting virus on my website https://www.siteguarding.com/security-blog/how-to-stop-a-mobile-redirecting-virus-on-my-website/ Tue, 07 Jul 2020 07:25:17 +0000 https://blog.siteguarding.com/?p=654 Read More]]> What is that and how it can damage your business

Malicious mobile redirect is a virus attack that activates as soon as a user visits an infected website from a mobile device. That is why the majority of website owners who view pages of their web resource mainly from stationary computers often do not even suspect that their web resource is infected and threatens the safety of users, and the company’s reputation, meanwhile, along with customer loyalty, is systematically moving down the drain.

Today, even if your business is not focused on mobile users, you need to pay attention to protecting your resource from mobile viruses and redirects. The mobile Internet audience is in the millions and continues to grow every year. Hackers earn fabulous money by infecting tablets and phones with mobile banking trojans, redirecting mobile visitors to WAP affiliates, etc. Therefore, any resource visited in the slightest way represents a tasty piece of the pie that the attacker is targeting.

Are there malicious redirects on my website?

To competently deal with a problem, it must be defined. You don’t have to guess that someone is “stealing” your mobile users until someone complains or you accidentally stumble upon the results of malicious scripts.

Unfortunately, messages from visitors can carry little useful information and cause panic, so here are a few measures you can take on your own:

Open the site on your smartphone and see if you get to another resource
Study the feedback of visitors and pay attention to their complaints, if necessary, you can clarify with them the details of the infection they encountered
Track the actions of visitors and analyze site statistics (you can also use different webmaster tools)

How to remove malicious redirects from your site

So, you found out that your site is infected, and the target of the hacker is mobile users. To start removing viruses on the site, first of all, you need to calculate their location.

Malicious code often looks like this:
RewriteEngine On
RewriteCond %{HTTP_REFERER} .*google.* [OR]
RewriteCond %{HTTP_REFERER} .*bing.* [OR]
RewriteRule ^(.*)$ http://malicioussite.com/index.php?t=6 [R=301,L]

Such redirect rules will redirect users from Google and Bing search engines to malicioussite.com. In general, everything related to Rewrite is worth checking where the redirect goes.

You can also manually check the following places on your site:

/index.php
/WP-config.php (for WordPress)
/configuration.php (for Joomla)
/wp-content/themes/yourtheme/functions.php (for WordPress)

Remember that malicious inserts are most often encoded and you will have to carefully look for fragments that seem suspicious in these files.

Malicious code can be placed by a hacker in various components of the site and can be either static (unchanging) inserts of malicious code, or dynamic ones that change and are encrypted in order to complicate their detection.

Let’s review most popular of them.

Static:

templates
scripts (e.g. JavaScript);
server configuration files;
database;
loaded as 3rd party components.

Dynamic: complex obfuscated JavaScript or polymorphic fragment that is generated using PHP, PERL, Python scripts.

Dynamic malicious redirect can substitute different domains into the code to which redirects take place. That’s the way how malware mobile redirect works. Thus, if you open a site infected with a redirect several times, you will often be redirected to various sites.

Dynamic injection can be performed by infected server modules. If a hacker breaks into a dedicated server, then he can introduce a malicious module of the Apache web server or the caching nginx server. In this case, when generating the page “on the fly”, a fragment of some JavaScript’s will be substituted, which will infect site visitors.

To detect malicious redirects and directly deal with the removal of viruses on the site, you must recreate a test environment that would simulate a user visiting a web resource from a mobile device.

Test environment setup:

Internet access through a 3G or LTE channel to catch mobile redirects that are activated only for users of mobile Internet;
traffic sniffer (Wireshark, HTTP Sniffer, Fiddler Web Debugging Proxy, Charles Web Debuging Proxy);
The User Agent field of the browser should be set as on the mobile (moreover, the same value should be available from the javascript of the Navigator object);
clean cookies (some codes use cookies to track the number of times a malicious code was displayed to a particular visitor, therefore they are inserted only once to one user accessing from the same browser).

After the test environment is ready, shoot the HTTP session in the HTTP sniffer, analyzing the chain of malicious redirects to the infected website and start looking for what code caused the transition.

The algorithm for malicious mobile redirects removal:

analyzing the recorded HTTP session, we find out what code caused the browser to redirect visitors to a third-party site;
look for a malicious fragment in the files on the server, for example, by searching for the detected fragment in all the files on the site;
find the virus code that generates the mobile redirect and delete it.

Treat the cause, not the effect

It is important to understand that removing viruses on a site is always a fight against the consequences of hacking and infection! The main task is not only to find and remove malware, but also to establish the cause of the infection – to find vulnerabilities (on the site or server) and eliminate them. And then put protection against hacking the site so that later the viruses on the site and hacker attacks are not afraid of you.

If it is difficult for you to remove mobile redirect malware from the website yourself, contact a specialist.

Mining Malware Detection and Removal Tips https://www.siteguarding.com/security-blog/mining-malware/ Tue, 20 Feb 2018 15:49:59 +0000 https://blog.siteguarding.com/?p=503 Read More]]> The hidden mining for cryptocurrency is not a new topic, although there are almost no worthy technical instructions for its detection and elimination. There is only a lot of scattered information and articles of doubtful content. Why? Because everyone benefits from mining world-wide cryptography, except, of course, the one who does not get a penny from this and does not even suspect that he has become a part of the global computer network.

How does it work? It’s simple – without the knowledge of the user, for example, when you open any file, the malware mining script is installed, which is connected to one of the mining pools and begins to produce cryptocurrency. Mining pools often choose the most appropriate option for a specific hardware configuration by themselves among them there are: coinhive mining script, monero mining script, Java Script miner.

Payments are made to the information in the “employer” account details, and he has the right to connect to his account any number of PCs, and no one requires him the evidence that they belong to him or their owners have approved this action.

That’s why pools are an ideal option for creating your own mining network (botnet). And they are doing it now (or trying to) all of whom are not lazy – from pros to schoolchildren, regulars of all sorts of “dark forums” with plums of “trouble-free and tested” schemes.

How to detect and remove

If you notice when you visiting any site that your computer has started to make noise and get warm, then most likely there is a hidden mining on this site. Look at the CPU usage statistics, when the processor is mined the processor will be heavily loaded. Then you need to scan the entire system for viruses and malware. However, these measures, which you can undertake by your own, are extremely superficial.

An integrated approach to solve the problem is needed. SiteGuarding.com company solves this problem quickly and effectively.

How to Clean Website Malware https://www.siteguarding.com/security-blog/how-to-clean-website-malware/ Thu, 03 Nov 2016 04:10:26 +0000 https://blog.siteguarding.com/?p=371 Read More]]> website malware clean

Do you suspect a hacker attacked you? Are now thinking on how to clean my website from malware? You got to the right place. We will explain to you how to clean up malware for inexperienced users. Every day hackers get into websites and block to infect them to spread more infections.

There are some other more complex cases, in which other features are exploded. A deeper technical knowledge is needed to get rid of those menaces. To enhance your security is important once your site has been compromised. You can follow some security best practices on password protection, form filling, and security updates.

Unfortunately, that is not enough for advanced hackers. They already know how to go around most security measures to break a site. Advanced protection like antivirus for websites and continuous monitoring services is advisable.

The Hidden Menace

Hackers are aware of people looking for strange things embedded on their web pages. The suspicious text will immediately lead to looking on how to clean my website from malware, and then they won’t be able to use that particular site anymore.

Even novice hackers will use a particular attribute to display malicious links. The display=none attribute will prevent visitors and site owners from finding the intruder links. Nobody looks for how to clean up malware until they have irrefutable evidence of a problem.

A naked human eye cannot see the malicious links, but search engine bots can. You can get de-indexed from search engines like Google if such links are found. It is easy to find the unwanted links, but you have to look for them. Here is what you should do:

  1. Open your source code on a web browser.
    • Most browsers let you go to the Page Source under the View menu.
  2. Check for the and tags for strange links.
  3. Look for links next to the “display=none” attribute.

If you know your code, then you will quickly identify the links that should not be there. If this is the first time you are looking at it, the malicious code will usually lead to porn or gambling websites. You can check the links you found or if they are obvious, just ban them.

To remove the unwanted links, you have to change the existing files, eliminating the unwanted links. Once you have changed it, double check if the links are really gone. If you have not identified the source of the infection, it is a good idea to change your admin password. Make it a strong one to avoid further intruders inside your site. Also, change the FTP password and set the file permission (chmod) attributes to read only.

To make a fresh installation of WordPress or any other software you are using to manage your site is advisable. This will ensure no injected files were left in the previous attack. But again, there might be a security issue left.

All these actions might prevent further intrusions to your website. However, some other vulnerability could have been exploded. Check if you have the most recent updates and look in a couple of days if your code is free of unwanted links. Take another week before you can declare victory over the links you just eradicated. If the problem continues, it is best to look for professional help.

Google’s Diagnosis

To identify if you need to clean up malware from your site, you can look at Google’s diagnosis from your website. Google ranks if it is safe to browse on your web page. To view your report, go to the following place:

http://www.google.com/safebrowsing/diagnostic?site=[SITE NAME]

Before you enter the address in your browser, change the [SITE NAME] to your site address. You will be able to know if you need assistance on cleaning website from malware, but Google will not display the sort of malware you have been attacked. You can try to scan your website with our free scanner or use Norton free scan. You can make a free website scan here:

https://www.siteguarding.com/en/sitecheck

http://safeweb.norton.com/

If you have a problem, our scanner will give you the solution. Norton has a broad range of products for end users and websites.

Closing Advice

Every malware is different, and you should get professional help who know how to clean up malware. Most times, when a site has been compromised, there are symptoms you can see. However back doors can be left even after you have cleaned your site from those symptoms.

It is important to contact the experts and get a deep cleaning. Get them to continuously monitor your web page. Even if there are no visible symptoms, and you just have occasional low performance, you can be infected. Hackers use your computer power to host sites, redirect traffic, commit fraud, send spam or any other possible criminal activity you can think of. They might not want to address you or your visitors, and those are the worse infections.

To remain unseen is the objective when your website is used for criminal activity. It can lead to legal issues to the rightful owner. While the investigations are taking place, your site might be closed, and you will lose ranking and traffic. It is better to prevent than regret. Besides following the best practice on security for websites, get a professional company to monitor your page.

virus detection

Your website needs to get protection from hackers. Think about your web page like a retail store. It is open to everybody, and some criminals might target it. The way hackers take over a website is by installing malware on it. Nobody wants malware, and you must regularly scan your website for malware, backdoors, viruses. To check website for virus is also important. Most antivirus has some malware removal tools, but the website malware check also addresses other problems.

All these measures are useful, and many vendors offer different solutions to their portfolio. We will explore siteguarding.com, because it has proven to be one of the most reliable vendors available, working since 2008 to keep malware out of websites.

However, we haven’t still mentioned what may happen if you ignore malware and keep on working as if it doesn’t exist. First, let’s go deep into this subject.

How Can Malware Affect Me?

If you think your website can live with malware, and there is no need of a website malware check, let me explain some of the most common shortcomings from malware:

  • You can get blacklisted by the main search engines (like Google).
  • A period of 7 to 10 days is the average recovery time for a malware attack.
  • Reputation damaged.
  • Legal issues when sensitive information is stolen.
  • E-mail might be blocked as spam.

To avoid all these issues you must regularly check website for virus. This way you can keep on doing online businesses without any setback. Other security measures like Joomla and WordPress are not enough to protect your website. The security provided by most host services like firewalls and DLP systems are not suitable for malware. New attacks are using specific vulnerabilities in the code, and that is part of what website malware check is all about. To keep pace with all these problems, expert engineers in companies like siteguarding.com can help you to protect your site.

How an Antivirus for Website can protect me from Malware?

A website antivirus is the minimum necessary protection for any web page. It doesn’t matter if it has thousands of daily visits or just a few, hackers can target it. The most frequent attacks seek to get access to the administration console, or spread spyware and other viruses to visitors.

The best way to address online menaces is by going to the source: the code. Most standard products on the market use a database that is continually updated to detect known menaces. The problem is that Internet has spread in such a way that there are hundreds of new threats identified every day and some advanced worms that change themselves over time. When you check website for virus by analyzing the code, it is easier to find new and mutating malware. One of the current leaders in the market to take this approach is siteguarding.com. They also have a team of engineers to analyze newly discovered menaces to develop a “cure.”

The main highlights you have to look for when you select a company for website malware check and virus removal are:

  • The ability to scan the code in every file.
  • CMS support.
  • Daily database updates.
  • Daily site scan.
  • A heuristic algorithm to find unknown threats.
  • A team of experts to back up the product.

In our research, the strongest company fully compliant with all these features for an antivirus for website solution was siteguarding.com.

Why do I need Scanning and Monitoring Services for my Website?

If you have antivirus software to check your site for virus regularly, then it makes no sense also to get a service to scan and monitor your site. It is used to strengthen your website malware check ability. Malware and any other web-based attack use your sites’ vulnerabilities. An antivirus can check for viruses and malware, but it cannot prevent reinfection. A website scanner is a smart solution to get into your site, identify infections and backdoors left to implant malware on it.

Antivirus does not necessarily detect some of this sort of infections, and a scanning tool cannot detect viruses on your website. Then, they complement each other to close the security circle around your web page. The kind of threats identified and eradicated through a scan and monitor service are:

  • JavaScript code injections
  • MySQL code injections
  • IP Wrapping
  • XSS (Cross Site Scripting)
  • PHP Mail services (to send spam under your name)
  • Community Attacks (attacks through social networks)
  • Website Vandalism (to get your site appearance changed)
  • Out of sight iFrames (to get your visitor’s computers infected)
  • Anomalies, phishing, redirecting, backdoors, .htaccess and drive-by-downloads

At siteguarding.com you can get a free scan (visit www.siteguarding.com/en/sitecheck). To help on removal, they have some of the most competitive packages on the market. You can also schedule daily scans for continuous protection. All packages include website antivirus protection and active monitoring services.

What if I find Malware? How do I clean it?

Depending on the menace, there are different procedures and preventive measures to clean your site. To get advice from professionals is highly recommended. If you try to clean it yourself, it will continuously get re-infected.

It is better to get a service for website malware check to eliminate malware and close backdoors and other vulnerabilities. To check website for virus on a daily basis is also a must. Among 10 of the most known vendors available, siteguarding.com proved to be a complete solution and at an affordable price. Most detection services you can get for free, and get continuous protection can cost less than 10 EUR. On some packages, you can also get malware removal.

Think about the revenue that comes every day through your web page. Is it more than 10 EUR? If the answer is yes, then you must get a protection package. The monthly inversion is less than your daily revenue, and it can prevent your web page from going down for a week or more.
