Ever wonder why you see “Warning! This site may harm your computer” or “Reported attack site!” on Firefox.
Well I was reading a couple of articles and finally figured out how Google determines this.
Google, which is a StopBadware.com partner, developed a system for automatically identifying many of these badware sites, and they worked with StopBadware.com to develop standards and an independent review process to ensure this system would remain accurate and fair.
When Google detects a badware site, it inserts an interstitial page titled “Warning! This site may harm your computer” when users try to access the badware site via Google’s services (search results, Chrome browser, Google Desktop, etc.).
Google also makes it possible for third parties to check URLs against Google’s list. Firefox, for example, uses Google’s Safe Browsing API and shows an interstitial page titled “Reported attack site!” when users try to access a site that Google has detected as bad.
