Hi,

What is the best way to remove viruses from a Windows machine?

Forgot to write down the message, but how I know there was a virus was because my wallpaper was changed to "You have been hacked" or something like that.

I've tried reinstalling the OS several times but that doesn't seem to help.
Somehow the virus still seems to be there. (i.e machine is slow and some unknown exe is always trying to access the internet). The exe name is something like ,,,,55786.

Please enlight.

Thanks,
Tee
