h0h0 you are screwed.
Most likely sub7, they just renamed server.exe (the virus) to a different name and made it a different icon.
Go to start>run>win.ini
see if there is anything after "load=" or "run=".
Heh, it is fun to sub7 yourself and play around with the features. You just have to remember to hit the remove button when you're done playing around.
