@Cashcannon:
You can remove...
R3 - Default URLSearchHook is missing
O4 - HKLM\..\Run: [QuickTime Task] "C:\Program Files\QuickTime\qttask.exe" -atboottime
O4 - HKLM\..\Run: [mmtask] "C:\Program Files\MUSICMATCH\MUSICMATCH Jukebox\mmtask.exe"
O4 - HKLM\..\RunServices: [Sasser Patch v1 ] msconf.exe
O4 - HKCU\..\Run: [Sasser Patch v1 ] msconf.exe
O23 - Service: Network Monitor - Unknown owner - C:\Program Files\Network Monitor\netmon.exe (file missing)
The 2 references to the Sasser patch stand out at me. It is possible that you have a virus because you also complain of 100% CPU usage. I found one virus write up that might fit the bill for you.
Read This and download the removal tool zipfile attached to this post. Remove the tool from the zipfile and run it. Let it remove anything it finds.
Then update your antivirus software definitions and do a full scan of your computer.
Then scan your computer again with hijackthis! and post a new hijackthis! log here.
