Query: Avoid Norton.

It was a happy day when I finally uninstalled Norton 2007. Instantly, my computer came back to life. I've had six months of nothing but slow start-ups, endless load times, and programs that either quit on their own or wouldn't quit when I wanted them to. Enough! I dumped them. And I used to be a happy Norton customer. But no more. Do yourself a big favor and avoid this one. If you're looking for some good anti-virus software I recommend AVG. But Norton doesn't deserve your business. All they deserve is a kick in the pants.
