I used to use McAfee, until a little over a year ago when I had the most difficult time getting decent support for an issue. I got so mad at them for not reading e-mails carefully. It even went as far as a supervisor, but I still did not get resolution. I wasn't asking for much, just answers to my questions.
At that point I decided that it was stupid to pay $30-40 per year for something and not get support. What else was I paying for? Just virus definitions?? That is when I discovered Avast.
My friend ran into a similar problem with Norton. She was having LiveUpdate problems. They helped her for about 4 e-mails, then realized that she was using NIS 2003, which is no longer supported, so they cut her off. Even though she was past the time to get a refund (she had just renewed a couple of months ago) she still wanted me to get rid of it and go with Avast also.
I used to be a die hard PC-Cillin fan (back from around 1998-2002). That was a darn good product, then they went and got all too big for their britches too.
