Google Ads May Sometimes Be Malicious

Google was apparently fooled into selling keyword ads to password thieves.  An article in Forbes describes the technique of using ads for legitimate companies that would first send clickers to a Russian site which would download a program that recorded passwords.  Google has removed the bad ads, but others speculate the thieves will try again.  Google being the biggest ad seller is the best target, but don't discount the possibility that other sellers such as Yahoo! or Microsoft won't end up as targets as well.
