virii sending and receiving data

[Tack]

Hi

a long time ago i posted an identical thread to this-

My dial up connection is constantly sending and receiving bytes, even when im doing NOTHING

The answer is virii of some description (mostly in windows/system .. exe files) are sending shit to their servers

anyway, i remember last time u guys gave some good tips and i managed to track down the culprits and delete the virus

any suggestions? (ie when i alt-ctrl-del what are the essential programs that should be running)

cheers for any help
