here's the dilema for us in the UK. i purchased a mcafee virus scan with VERSION 5 on the box; and was suprised to find the scan engine is 4.10 and the dat files are 4.x

the thing is, I already had 4.03 scan engine and was using 4.x dat files.

when i complained to mcafee they said this was standard numbering. the customers in the US get the real v5., while everyone else gets v4...
