About a year ago, I noticed that my computer was running slow (both online and off) and that the explorer.exe process listed in the Windows Task Manager was usually running very high. Windows Explorer seemed to crash a lot as well. A few months ago, I attempted to install Kaspersky Internet Security 7.0 on my computer and before the install completed a warning window popped up saying something like 'there is already another instance of Kaspersky running' (which was not the case since this was the first time I had ever attempted to install Kaspersky software) and the install failed. When I rebooted my computer, I got the blue screen of death for a few seconds and then Windows booted with a message saying that Windows had recovered from a serious problem. Since recovering from whatever happened after the failed Kaspersky install, my computer is slower than ever and the Task Manager still shows a high CPU usage even though the System Idle Process is high and there isn't any processes listed that are using much CPU time at all.

I just scanned my system with the latest updated versions of AdAware, Spybot S&D, SuperAntiSpyware, and Avira AntiVir. All of them found nothing. I then cleaned my computer with CCleaner and ran HijackThis.

Here is the log:
