Hi lmcashen, the DAT is included in VirusScan and not in McAfee Agent. This was done this way because in the past McAfee delivered a VirusScan package with the DAT file at the day the package was created and so it was outdated when downloading it 3 months after.
The other problem is that VirusScan with any outdated package is about 130MB and the one without DAT (the 1111 DAT is a fake DAT) is about 40MB
If you want to create a VirusScan package including a newest DAT you may use the McAfee Install Designer for VirusScan 8.8
