No beta version, no external drives, roughly 45 gigs that should not take days to scan. After 10 hours, it was only half done! I stuck Sophos on my little backup Mac, and it scanned 22 gigs in a half hour.
I'm trying to do an in-depth scan, but it seems to take forever, or it just stops and doesn't continue. I have set my computer sleep setting to "never" thinking that maybe it paused when the computer went to sleep, but even after 10 hours it only shows it half done.
