WordPress Malware Removal Guide

Discovering malware on your WordPress site is alarming but recoverable. With a systematic approach, you can clean the infection, restore your site, and implement measures that prevent recurrence. Speed matters — infected sites get blacklisted by Google and hosting providers.

Symptoms of WordPress Malware

• Google "This site may be hacked" warning in search results
• Hosting account suspended due to malicious activity
• Unauthorized admin user accounts appearing
• Site redirecting visitors to spammy or malicious URLs
• Spam content appearing in Google Search Console
• Unexpected PHP files in the uploads directory
• Slow site or unusual server resource usage

Step 1: Take the Site Offline

Enable maintenance mode immediately to prevent visitors from being exposed to malicious content and to stop the malware from spreading or executing further. Inform your hosting provider — they may have already detected the issue and can assist with cleanup.

Step 2: Scan for Malware

Use multiple scanning tools for thorough detection: Wordfence (install and run a full scan), MalCare (cloud-based scanning that doesn't load your server), and Sucuri SiteCheck (external scan from a different perspective). Cross-reference results — different scanners detect different malware families.

Step 3: Clean or Restore

If you have a clean backup from before the infection, restore from backup — it's faster and more complete than manual cleaning. If no clean backup exists, manually remove infected files: delete and reinstall WordPress core, delete and reinstall all plugins and themes from official sources, manually review and clean theme and plugin files that can't be replaced cleanly.

Step 4: Change All Credentials

After cleaning, change every password: WordPress admin accounts (delete any unauthorized users), FTP/SFTP credentials, database password, hosting control panel password. Generate new secret keys in wp-config.php using the WordPress secret key generator. Invalidate all existing sessions.

Step 5: Harden and Monitor

• Update WordPress, all themes, and all plugins immediately
• Enable two-factor authentication on all admin accounts
• Install Wordfence or Sucuri for ongoing monitoring and firewall protection
• Remove inactive plugins and themes (deleted, not just deactivated)
• Set up file change monitoring alerts

SiteICO's container isolation ensures that if one site on the platform is compromised, it cannot affect other sites. Each WordPress installation runs in an isolated container with its own process space.
