We've got good news. Today, before my brother turned off his computer, I took a look at the File System Shield: Scanned files/Infected files: ~1000/
0!!. Looks like ComboFix caught that virus. We'll test the computer for two more days to be sure that it's gone. I'll tell the results
Oh, and I'll upload the zip with the other virus - could this "AutoIt:Balero-B"
worm serve the other one? - That "is-..."'s name was Setup/Uninstall (Fake software!?).
Thank you very much, essexboy!
