I downloaded a free antivirus from AVG today and am testing it on my daughter's computer. Why? Because I'm sick of McAfee.

I have been using McAfee Anti-Virus since v. 2.0. Each year I got more and more dissatisfied with the product, but I kept using it because I could get it for virtually free after rebate. In recent years, actually getting the rebate became a challenge. Thankfully, I keep photocopies of everything, but it was still a pain to resubmit everything each year because they claimed they only received half of what I really sent.
This year, they went too far. I started to fill out the rebate form just now. One of the requirements was that I send in the proof of purchase located on one of the inside flaps on the top of the box. I opened the box, but both tabs were blank. In previous years there has always been a proof of purchase on one of the tabs. I guess McAfee came up with a new way to ensure they don't pay out many rebates.
