IE Slow to Load Pages

I have a computer that is Windows XP SP2 and IE is slow to load pages and doesn't completely load them all the time. This started when I was having problems with Norton so I removed it and installed AVG. I upgraded from IE 6 to 7 and it didn't help...the only thing that helps is removing AVG. So I installed PC-Cilling...same thing. So when any anti virus is loaded the internet crawls, but once you remove anti virus it flies. Could there be a reminent of Norton causing this? Help!

 

Do you have any IE add-ons enabled? Also, have you tried installing anti-virus software and using a different browser to see if you get the same performance problems?

Also, have you tried emptying the browser cache and cookies?

Peace...
