Hi to all. Have Windows XP Prof. Also have latest McAfee 8 Antivirus with ALL it,s latest updates, also have NO retore points. I have "W32/Sdbot.worm.gen.g" in my Windows System32, McAfee has deleted it nine times. I go onto Windows, scan it, McAfee picke up and deletes the worm, then after using the computer for a short while it goes very slow or freezes.If I can get into Windows and scan it again, the worm is back. Your help would be great. Thank you.
