Google Malware Checker
The Google Malware Checker is a free online security tool that checks whether Google has flagged any website as dangerous — containing malware, phishing pages, unwanted software or deceptive content. Google's Safe Browsing service analyzes billions of URLs and updates its database regularly to protect users from harmful websites.
If your website appears in the Google Malware database, visitors will see a red warning screen ("This site may harm your computer") before reaching your site — effectively destroying your traffic and reputation. Regular malware checks help you detect and remediate infections before they impact your rankings and visitors.
How to Check for Malware
- Enter your website URL
- Click Check for Malware
- The tool queries Google's Safe Browsing Transparency Report
- Results show: Safe, Unsafe, or Suspicious
What to Do If Your Site is Flagged
- Immediately scan your server files for malicious code injections
- Check recently modified files for unauthorized changes
- Remove infected files and restore from a clean backup
- Update all CMS, plugin and theme versions
- Change all FTP, database and admin passwords
- Request a review through Google Search Console after cleaning
