Expert Injected JavaScript & Obfuscated Code Removal
Same-Day Malware Cleanup | SEO Spam Recovery | Forensic Analysis
Malicious JavaScript destroys user experience, hijacks browsers, steals form data, and tanks your SEO. Our specialists remove obfuscated code, eliminate cryptominers, clean SEO spam, and restore your site's integrity with forensic-grade remediation and root-cause fixes.
Why Injected JavaScript Threatens Your Business
Client-side malware operates in browsers, hijacking user sessions, stealing credentials, damaging SEO, and destroying the trust that took years to build
Malicious Redirects & Popups
Injected scripts redirect visitors to phishing sites, display fraudulent popups, and serve malicious advertisements that kill conversion rates and damage brand reputation through association with scams.
Cryptominer Resource Drain
Hidden cryptocurrency mining scripts consume visitor CPU cycles, causing browser slowdowns, device overheating, and battery drainage. Users abandon slow sites, directly impacting revenue and retention.
Session & Credential Theft
Form-hijacking JavaScript steals login credentials, payment information, and session tokens. Attackers exfiltrate sensitive data to remote servers, creating legal liability and compliance violations.
SEO Spam Injections
Malicious scripts generate doorway pages, inject hidden links to illicit sites, and manipulate sitemaps. Google detects these patterns, resulting in manual penalties, blacklisting, and devastating traffic loss.
Browser Warnings & Blacklisting
Chrome, Firefox, and Safari display red warning screens when detecting malicious JavaScript. Google Safe Browsing flags your domain, preventing visitors from reaching your site and destroying organic traffic.
Payment Processor Suspensions
E-commerce sites with injected checkout scripts face immediate account freezes from payment processors. Lost revenue during suspension plus customer notification requirements create massive business disruption.
Common JavaScript Injection Methods We Remove
Understanding how attackers inject malicious code helps us locate and eliminate every infection point
Inline Obfuscated Scripts
Heavily encoded JavaScript injected into HTML templates, headers, footers, and widget areas. Uses base64, hex encoding, and character substitution to evade detection while executing malicious payloads.
External Script Inclusion
Attackers inject <script> tags loading code from compromised domains or hijacked CDNs. Scripts appear legitimate but deliver redirects, popups, cryptominers, or data theft functionality.
Dynamic DOM Manipulation
JavaScript that modifies page structure after load, injecting iframes, hidden forms, or overlay elements. Creates invisible page layers that capture form submissions and steal credentials.
Third-Party Library Tampering
Compromised jQuery, React, or other popular libraries with backdoors embedded. Legitimate-looking code contains hidden malicious functions that execute across your entire site.
Database-Injected Scripts
Malicious code stored in database tables (posts, options, widgets, custom fields) that renders on every page load. Difficult to detect without comprehensive database scanning.
SEO Spam & Doorways
Scripts generating thousands of low-quality pages targeting keywords, injecting hidden backlinks, and creating doorway pages that redirect based on user agent or referrer detection.

Common questions about JavaScript malware removal and our service
For visible single-file injections affecting landing pages, we often achieve same-day remediation. More complex infections involving database injections, obfuscated code, or multiple entry points typically require 24-48 hours for complete cleanup. Emergency triage and containment (maintenance page, WAF rules) can be deployed within hours to stop active malware delivery while we perform comprehensive removal.
No. We stage all changes carefully, create complete snapshots for rollback protection, and validate functionality throughout the cleanup process. Our specialists distinguish between malicious and legitimate JavaScript, ensuring essential features like forms, checkout, analytics, and interactive elements continue working. We test thoroughly before declaring cleanup complete.
Yes. Our remediation report includes before/after file hashes proving changes, scan outputs from multiple security engines showing clean results, list of all modified files and database entries, behavioral verification confirming malicious actions stopped, and forensic evidence suitable for insurance claims or compliance audits. You receive complete documentation of the cleanup process.
Absolutely. Our security engineers are experts in deobfuscation techniques including base64 decoding, hex conversion, Unicode escape sequences, and advanced packer reversal. We decode the malicious payload to understand its exact function, then surgically remove only the harmful code while preserving legitimate obfuscated scripts (like minified libraries) that your site needs.
We can begin with remote triage identifying visible JavaScript injections through browser inspection and external scanning. However, complete cleanup requires file system and database access to remove persistence mechanisms, clean injected database content, and verify no hidden backdoors remain. Most hosting providers readily grant temporary access for security remediation work.
Yes. SEO recovery is included in our service. We remove all doorway pages and spam content, clean sitemaps and robots.txt, prepare detailed evidence packages documenting cleanup, submit reconsideration requests to Google Search Console, coordinate with Safe Browsing for blacklist removal, and monitor recovery progress. Most sites see ranking restoration within 2-4 weeks after Google review.
Reinfection typically means the root vulnerability wasn't addressed. Our service includes root-cause analysis and hardening to prevent recurrence. We identify how attackers gained access (compromised plugin, weak credentials, file upload vulnerability), patch the security hole, rotate credentials, and implement monitoring. If reinfection occurs due to the same entry point within our warranty period, we re-clean at no charge.
Absolutely. We work under NDA when requested, use private communication channels, handle credentials securely with no retention, coordinate discreetly with hosting providers and internal teams, and never disclose client information. Your business reputation is protected throughout the entire remediation process. Many enterprise clients appreciate our discrete incident handling.
We use multiple detection methods: signature-based scanning for known cryptominer libraries (Coinhive, CoinImp, etc.), behavioral analysis detecting mining pool connections and high CPU usage patterns, entropy analysis flagging heavily obfuscated code, network traffic monitoring identifying mining protocol communication, and WebSocket inspection detecting stealth mining connections. Our tools catch even heavily disguised miners.
Emergency service prioritizes rapid containment and visible cleanup: immediate triage assessing infection scope, lockdown procedures stopping active malware delivery (maintenance page or WAF), CDN cache purging preventing cached malware serving, removal of most visible JavaScript injections from landing pages, quick remediation report with rollback plan, and scheduling of follow-up deep cleanup for persistence hunting and complete hardening. Ideal for active crises requiring immediate action.
