I'm running AntiVir Premium. I know certain AVs perform scans differently then others. Some scan all the files within the archive. Some just scan the archive. I just ran a full system scan with AntiVir Premium. It scanned only 22,628 files, and only took 12 minutes to do it. I've never had an AV scan that few files, and never had one scan so quickly. As an example, NOD32 would scan approximately 128,000 files in about 45 minutes. I'm a little worried about whether AntiVir is doing it's job. I'm used to bigger numbers of files and longer scan times. Can this be a normal full system scan? My OS is XP Home/SP2, 40 Gig hard drive, if that matters.
