Norton really slows down the computer. I would recommend a registry clean asap to get rid of the extra crap it has added to your registry. Panda isn't as good as avg, but it's pretty close. It's a lot better than Norton though, that's for sure. I believe that AVG is the best because #1, it's free and #2, it runs in the background, but unlike Norton and many other anti-virus systems, it doesn't take up 35% of your computers processing speed to do it!

: However, AVG's anti-spyware has a protection program that always runs in the background. It's called "guard.exe" in the task manager and you can't end it. It takes 2.4ghz of processing power! I'd rather have the spyware than the Guard.exe program!

: Does your panda come with anti-spyware too or is it just the anti-virus edition? BTW, it is never a good idea to have more than one anti-virus system on your computer at one time. That's why you were advised to remove them. Also, unless you manually update AVG, it's useless. If panda found more than avg did, then it's probably cuz AVG wasn't updated. Even when it says it's updated, it's not. You have to manually do it. It may be a pain in the you know what, but it does provide the best protection. I'm not suggesting you switch. Panda is fine (not to mention that you paid for it). I would get panda, but I'm too cheap and AVG is better so long as you can spend 2 hours a week keeping it up to date manually. B)
