Google has developed a Safe Browsing or Anti-malware diagnostic page that will provide detailed information about automatic investigations and findings to protect Google users from visiting malicious web pages. The Safe Browsing diagnostic page of a site is structured into four different categories:
- What is the current listing status for [the site in question]?
- What happened when Google visited this site?
- Has this site acted as an intermediary resulting in further distribution of malware?
- Has this site hosted malware?
All information we show is historical over the last ninety days but does not go further into the past. Initially, we are making the Safe Browsing diagnostic page available in two ways. We are adding a link on the interstitial page a user sees after clicking on a search result with a warning label, and also via an "additional information" link in Firefox 3's warning page. Of course, for anyone who wants to know more about how our detection system works, we also provide a detailed tech report [pdf] including an overview of the detection system and in-depth data analysis.

You can append any domain, you want to check on to the end of the URL “google.com/safebrowsing/diagnostic?site=xxx.com", or paste a domain in the box below, and you will find an overview page listing potential problems like trojans or exploits (or the result may be telling you the site is OK).
Here's the diagnostic page for google.com: http://www.google.com/safebrowsing/diagnostic?site=google.com, which lists some interesting facts.
Of the 387253 pages we tested on the site over the past 90 days, 4 page(s) resulted in malicious software being downloaded and installed without user consent. The last time Google visited this site was on 05/23/2008, and the last time suspicious content was found on this site was on 03/13/2008.
