Im pretty sure you all are aware of the viruses p2p can give you.
Well i stumped onto this neat virus today. When it runs, it makes about 30 more of the virus in ur shared folder with differnt RAR names.

For example
Black and white
Clone Cd
Jarhead

and when poeple downloaded these, and ran the exe, the virus would open and start making more rars with differnt program names. I didnt notice i had the virus untill 10 mins ago.

Sorry to say, it said about 100 people total already downloaded some programs off me.

I have no clue if it has other effects on your computer, but i know when i had it, my computer was slow, IE barly worked, and it ate up all my internet connection.

Anyways, do your best to remove these types of programs limewire!
