New Yahoo IM Worm Poses as 'Safety' Browser

First discovered by anti-malware researchers at FaceTime Communications, the worm, labeled as yhoo32.explr, is forwarding itself throughout Yahoo's IM system via the contact lists of people whose computers it has already been infected. Once loaded onto a PC, the malicious program automatically hijacks the computer's existing browser home page and encourages users to visit a fraudulent Web site that attempts to load spyware programs onto their devices.

More fun and games from the bad guys.
