Koobface worm threat to Facebook, MySpace and Bebo

A new variant of the Koobface worm has begun spreading on social networking sites.

Beware if you get a Facebook, MySpace or Bebo message from a friend that contains a link to a YouTube video. On clicking the link you are taken to a site 'supposedly' hosting the video posted by your friend.

This page will actually contain their name and their use their Facebook/MySpace/Bebo profile picture. From there you will be prompted to install a setup.exe - DON'T DO IT!

Other sites that seem to be at risk are: Friendster, Tagged and LiveJournal.
