Common Warnings and What They Mean
- "Deceptive site ahead" / Phishing Warning: The browser suspects the site is attempting to trick users into revealing sensitive information by impersonating a legitimate entity.
- "This site may harm your computer": The browser believes the site is attempting to install malicious software onto the visitor's computer.
- "The site ahead contains harmful programs": The site might be tricking users into installing software they don't actually want.
Why Does a Site Get Flagged?
- Website Hacked: The most common reason. Attackers compromise a legitimate website and inject malicious code.
- Malicious Advertisements: Third-party ads might contain malicious code (malvertising).
- Hosting Phishing Pages: The site owner might intentionally host pages designed to steal credentials.
What Website Owners Should Do
- Verify the Warning: Check your site status using the Google Safe Browsing tool.
- Scan Your Website Thoroughly: Use security scanners to identify malware or backdoors. Check all files and the database.
- Clean the Hack: Remove malicious code and change all passwords.
- Request a Review: Once certain the site is clean, request a review through Google Search Console.
