Just got home after a long day of removing a new virus variant from lots of PC's. It is called Sober-Y and comes as a zipped attachment. To activate the virus you must unzip it and execute the installer.

It comes with an email stating things about the FBI or Nicole and Paris Hilton. If you have virus protection software it will likely catch it if updated with the latest definitions.

In any event, if you get a zipped attachment, just delete it. Curiosity is a bad thing.
