Recently, my main system is not running as efficently as it has in the recent past. I have run Advance System Care 3, Spybot S&D, Ad-Aware, SuperAntiSpyware, Malwarebytes, a recent version of Kaspersky Virus Removal Tool and Bitdefender 10 (Freeware Version). All have come back negative. I have run diagnostics on all of my hardware components with the exception of my processor.
