I'm having a problem with Firefox, Thunderbird, and Internet Explorer hanging. I built my system a little over a year ago and am running XP with SP2. Initially, everything worked fine - the hanging problem seems to have started sometime in the last 4-6 months.


While using any of the above mentioned applications, I get frequent instances of hanging lasting 15-20 seconds when I launch the applications, open a new Browser window or tab, click a button to initiate a action, refresh a page, check for new mail, etc.

I'm running Comodo Firewall and also Comodo AntiVirus Beta. Have posted on the forums there but figured I'd post here too in hope of finding a solution.
