The Security Mentor

This is the message a really nasty piece of software sends out on MSN Messenger asking you to download it. It pretends to be a movie, but if you run it, it will send IMs to all your contacts tellig them to download it. Meanwhile, it will have disabled your antivirus software and wrecked several of the built in Windows tools that would be needed for removing it.

If you get a message like that inviting you to download a movie named Fantasma from a web page somewhere, don't take the bait. It's unclear from the published accounts whether there's a real movie that triggers a security flaw in the movie player software, or whether it's just a regular program that people are clicking on without looking.
