According to the Google security blog, the company already knows about hundreds of thousands of “bad” Web sites and hopes that users will add to the list by completing an online form to report malicious sites that are not already flagged. Google last year started flagging sites listed in its search results that contain malicious software. When a bad site is selected, instead of being sent to the site, Safe Browsing API shows a message saying, “Warning–the site you are about to visit may harm your computer!” Users then have the option to continue or return to the search page.
