Avast just found five billion viruses on my comp...

[SLLAB02]

This morning when I woke up, the Avast Antivirus window had popped up telling me a virus was found. I clicked "Move to chest" and immediately another one popped up-this continued for 20 or so times and so far has not stopped. It's finding trojans in my temp folder for ALL sorts of keygen files (for programs I did not download, most of which I have never even heard of). I suppose my roomates could have downloaded them when I wasn't around, so I'll have to ask them before I justify my state of panic...but in the meantime, has this ever happened to you guys??? Seriously - like TWENTY warnings came up, each for different crack.exe files in my temp folder. I'm scared! Help!
