Google Safe Browsing

What it checks

Whether Google Safe Browsing lists the home page, or the site's own pages it links to, as malware, phishing, unwanted software or harmful apps. Advisory provided by Google.

Why it matters

Chrome, Firefox and Safari warn visitors away from listed sites, and a listing usually means the site has been hacked. Google can't guarantee its lists are complete or free of errors.

How to fix it

1. Open Security issues in Google Search Console, which says what Google found and where.
2. Remove it, update everything the site runs, and change every password for the site and its hosting.
3. Then ask Google for a review from the same page.
