• Use FTP (FileZilla) or cPanel File Manager.

• Check recently modified files (hackers often alter them).

Step 2: Review Database for Malware

• Open phpMyAdmin (via hosting panel).
• Search for suspicious scripts in wp_options or wp_posts.

Step 3: Compare with a Clean Backup

• Restore a clean backup if you find malware.

Method 3: Online Malware Scanners (No Plugin Needed)

If you can’t access WordPress, use these free online scanners:

✔ Sucuri SiteCheck – Scans for malware & blacklisting.
✔ Quttera – Detects hidden malicious code.
✔ VirusTotal – Checks files against 70+ antivirus engines.

What to Do If Malware Is Found?

1. Quarantine & Remove Malware

• Use Wordfence or MalCare to auto-clean.
• Delete suspicious files manually via FTP.

2. Update Everything

• Update WordPress, plugins, and themes (old software is vulnerable).

3. Change All Passwords

• Reset WordPress admin, FTP, and database passwords.

4. Enable a Web Application Firewall (WAF)

• Use Cloudflare or Sucuri Firewall to block future attacks.

5. Monitor for Re-Infection

Best Practices to Prevent Future Infections

✅ Keep WordPress & Plugins Updated.
✅ Disable Unused Plugins/Themes.
✅ Regular Backups (Use UpdraftPlus or BlogVault).
