We’ve been targeting malware for over a year and a half, and these efforts are paying off. We are now able to display warnings in search results when a site is known to be malicious, which can help you avoid drive-by downloads and other computer compromises. If you come across a site that is hosting malware, please fill out this short form. Help us keep the internet safe, and report sites that distribute malware. The down side is that the iThugs will keep registering to other domains. However, that will be time and profit consuming.”]
