BleepingComputer.com: over usage of cpu showing in task manager

I apologize if this topic exists. I could not find it by searching.

My Sony Lap Top will begin to slow down and seems to click a lot. When I go to the task manager, WAOL is using up to 300k of my memory, which seems high. It is not always that high. Sometimes under 100. I have searched for malware, viruses, worms, all of the mess that could be in here. Do I have a leak, and how would I check for that? I run norton 360, adaware, I have pest patrol and malwarebytes or something like that. Also have registry cleaning software.

Thanks for any hints you may have.

You've tried uninstalling the AOL software...and then reinstalling?
