To tell you the truth Joe, you'll get a lot of different replys to that question. I personally use Zone Alarm Plus (firewall) and Panda (anti-virus). Both work great! I had some issues with Norton in the past which is why I use Panda now. Most of them do a good job, some might have issues on some systems, but for the most part they all do a pretty decent job.
Just my two cents...
