I'm confused (not an unusual situation). . .According to the box my McAffee VirusScan came in it's version 5 and according to the CD it's v 5.0.1. . .According to the home screen, the scan engine is version 4.0.50. It doesn't seem to tell me anywhere what version the program itself is.. .According to McAffee they are no longer supporting version 4.0.50, but is this of the program or the scan engine?. .. .Every so often, when I download an update it tells me that my files are very old and I need to download a complete new set. Other times it just downloads the latest update. There seems to be no logic.
