Well, McAfee has added this cool feature of not scanning folders which haven't been modified, which saves time. So let's say you love DVD's and have 30 saved onto your computer in a folder called "DVDs". Now when you scan it would help if DVDs wasn't scanned because it'd be very large. But this feature does this to any unmodified folder from one system scan to the next...quite resourceful if I do say so myself. Any plans on adding it?
