What should I do if my site has been flagged by Google Chrome as dangerous site? Ispis

If you own a site marked as dangerous or deceptive, you can change your website and must request a review from Google to have your page or site unflagged as dangerous or possibly deceptive to users.

You need to report this to Google if false positive. Here is the URL https://safebrowsing.google.com/safebrowsing/report_error/?hl=en-US
