If you’re seeing weird redirects, strange users, unknown plugins, or antivirus warnings—your site is likely compromised. This guide lists the most common symptom-based problems site owners Google right before they call us. We explain what each sign means, why it happens, and how to fix it quickly. If you want hand-off cleanup with a guarantee, our WordPress Malware Removal Service is ready 24/7.


Quick rescue checklist (do this first)

  • Change cPanel/hosting, SFTP/SSH, and WordPress passwords (all admins) + rotate salts in wp-config.php.
  • Put the site in maintenance mode if it’s aggressively redirecting or serving malware.
  • Take a full backup (files + database) before you touch anything.
  • Enable a Web Application Firewall (WAF) at the edge (your CDN or plugin) to block active exploitation.
  • Scan files and database; compare against clean WordPress core checksums.
  • Remove backdoors, fix file permissions, and update core, themes, and plugins.

When in doubt, skip to: We’ll clean it for you.


1) Redirect Issues

My WordPress site redirects to spam sites when clicked from Google

Meaning: Conditional redirects are injected to trigger only when visitors come from search engines.

Fix fast: Check .htaccess, wp-includes, functions.php, and any MU-plugins for obfuscated or base64 code. Remove malicious redirect rules and harden the server.

Likely causes: Infected theme/plugin, malicious JS in header/footer, .htaccess rewrite rules, or database-injected payloads targeting referrers and mobile user agents.

How we fix: Find the redirect source (server rules, JS, PHP), clean payloads, remove backdoors, patch vulnerable components, and set WAF rules against known redirect kits.

  • Remove unauthorized plugins/themes; check autoload options for persistence.
  • Search codebase for base64_, gzinflate, str_rot13, assert, preg_replace with /e.

FAQ (ranked for common searches)

Why does my website redirect to adult sites from search results?

Cloaked redirects target search-engine referrers. Clean .htaccess, remove malicious JS/PHP, restore clean core, and harden to prevent reinfection.

My WordPress site redirects to fake virus warnings (McAfee/Norton).

That’s scareware. Remove the redirect kit and block its domains; then request delisting with vendors.

Found a WordPress admin user I didn’t create—what now?

Remove it, rotate all credentials, and hunt for user-creation backdoors in functions.php/MU-plugins.

Japanese keywords in Google results for my site—am I hacked?

Yes, likely SEO spam. Clean DB + templates, regenerate sitemaps, and request reindexing.

.htaccess contains unknown code—safe to delete?

Back it up, reset to WordPress defaults, and reapply only known-good rules.
