Whats wrong with my computer, its slow and wont start up some programs?

October 21, 2009

I have avg installed, no viruses, used malwarbytes, no malware. Used a good registry cleaner(registry cleaner) all taken cared of, I did disk clean up, all good, I even tweaked with the virtual memory and its still slow. I even tried to install super anti spyware and i cant, I get some type of error. I even tried to do system restore, but the pc wont let me open it(turned of by group). Is it just that I need more ram? Because i tried to run disk defragment, but it never finished(maybe because Im using vista, and I dont have enough ram. A little help please?

How come at random websites I keep on getting virus protection pop ups?

I have McAfee virus protection plus "super anti spyware" program. I do the scan everyday, delete temp. internet files(cookies, etc.), clean my hard drive, and defragment it. I still get pop ups eventhough the pop up blocker is on, plus when these ads for a virus protection come up, they block pictures. Not to mention, I have two trojans to get rid of which are called Winfixer and Vundo..anyone know how to fix this? Any help would be greatly appreciated. Thanks!
