This kinda relates to: HiJack This Post
Basically, my girlfriend's parent's PC has been infected with spyware and viruses and i've pretty much tidied it up (i think) but the PC now runs slow from time to time. I have installed a fair few new programs such as AVG, Ad-Aware, etc which will obviously slow it a little but the problem i think lies elsewhere.
The most obvious example of this is when i look at the task manager and the performance tab, the CPU usage quite often seems to be stuck at 100%. Everything naturally runs slow when this happens.
Does anybody know what is happening and how i can fix it?
Thanks in advance .
