The Google Safe Browsing feature flags sites that may feature malicious content either in their coding or available downloads. It uses information obtained by an automated investigation system that looks for potential problems across the web. The data goes back to the past 90 days.

You can use the tool by going to http://www.google.com/safebrowsing/diagnostic?site=inqusitr.com, replacing inquisitr.com with the actual domain name in question. The function is also now integrated into the Google Toolbar extension for Firefox.

Yahoo introduced a similar feature earlier this month with its SearchScan program. That utility, though, uses data from McAfee’s SiteAdvisor rather than data collected by Yahoo itself.
