I've been seeing lately on several freeware sites mention of free virus definition updates to Mcafee (and other) Antivirus programs. From what I could tell, you simply copy the DAT files to your Mcafee DAT directory, and you're good to go. Now, I've been paying 29 bucks annually to Mcafee to deliver these updates to me via the internet. Is this necessary? Could I obtain the same data legally from a freeware site, and suffer only by having to locate the right directory to put them in?
