I just upgraded to NAV 2005 about a month ago. So I have time to get a refund if I choose. I had an old copy of NAV 2003 laying around. Upgrade price is $29.95. I'm a Comcast HSI customer and I was checking Comcast's homepage. I don't use it, so I don't go there very often. I discovered that they are offering McAfee VS9 to Comcast customers for only $29.95 for a one year subscription. Looks like a pretty good deal to me. If it weren't for that offer, I wouldn't even be posting this. I hate asking this question but,with the prices being equal and you had to choose between the two, which would it be and why? I'm a little disappointed with the way McAfee for the way they first announced that they were going to daily updates and then it turns out it's only for Enterprise users. But that's another topic. My OS is XP Home/SP2. Old 700Mhz computer 448RAM.
