I've just had a pretty bad virus on my comp which has been a right ball ache to get rid of, it calls itself "Vista Antvirus 2010" although the name changes depending on what operating system you have.
The little "windows update" symbol appeared so it all looked official at first, until it installed itself. It was the usual bollocks about purchase this and purchase that and you'll be safe for life shit.
Here is a screen shot of said virus in action:
Anyway, if anybody on here gets this same virus (apparently it's pretty common) then visit this website and follow the instructions on how to get rid of it.
