Well like you had problems with Norton. I had problems with Mcafee. The year was I think 2003 and all through the house not a creature was stirring not even a mouse. LOL a little joke. I think the year was 2003 and I think the Mcafee version was 7.0 and my mom bought it for me and I happily installed it. I was a Mcafee sheep back then involved on their forums. Although I had no idea what I was talking about. Their program gave me problems, blue screen of death over and over. I vowed never to use Mcafee again. Although I did.
The computer was 400 mhz, 64 mb ram, and an onboard graphics card believe it or not that computer tower was $1500 in the year of 1998 or 1999. It was a crappy computer, but the only computer I had at the time. You should of heard me ranting at the time about Mcafee, but I got over it.
Norton on the other hand. Symantec I used them too. Norton Antivirus 2000 the first antivirus I ever scanned with. I bought Norton Utilities 2001 (my dad did for me) and I loved it. The only problem is when I tried to get a redownload it took 3 months because our e-mail address changed and they had the old one, but they gave me the upgraded 2002 version for free.
Right now I use Norton Security Suite (works great) and System Mechanic. I been thinking about trying Norton Utilitues, but I also think it would be a waste of time because Norton Security Suite does most of that and I have System Mechanic.
