Had a computer that may have had a keylogger or other spyware on it. Did a fresh install of Windows 7. (HP Pavillion a1114n). Processor showed 100% utilization. Reloaded with XP w/SP3. Processor at 100%. Replaced hard drive with one from retired system. Reinstalled XP w/SP3. Processor 100%. Looked deeper and in task manager, with option for all processes to show, and running processes only total up to 10%. Idle shows between 90 and 100%. But processor utilization shows 100% and computer runs very slow. This was the same behavior in Windows 7 as well. I have never had processor not total properly... I am at a loss. Any ideas?
