Malware detection methods by Google search

[walter4h]

Hello everybody:
I did a search on Google for "Maria Sharapova".
I then clicked on one link and got this warning:
>>>
Warning - the site you are about to visit may harm your computer!
You can learn more about malware and how to protect yourself at StopBadware.org.
Suggestions:
Return to the previous page and pick another result.
Try another search to find what you're looking for.
Or you can continue to http://www.sexysharapova.com/.
advisory provided by Google.

I have never seen such a warning before. Does anybody know if Google actually checks all sites in its index for malware or do they have another source of this info?
Thx
walter
