Just formatted my system after it was invaded with some trojans. But now, AVG doesn't detect any viruses or malware at all, yet when I open Task Manager, my system CPU usage is hovering from 77-100 percent. Computer is running really slowly too.

Any ideas?

Right Click Task Bar>>select Start Task Manager>>Go to Process tab and select All Processes from ALL User Double Click CPU tab until the little arrow is pointing down

It should list the highest process name (CPU usage)
or

download this http://technet.microsoft.com/en-us/sysinternals/bb896653 -GUI program of Task Manager

Open it up.

same process as above

type the process name in your next reply or a screen shot its your choice.

Usually System Idle Process is the highest one 96-100% or bouncing in between there System Idle Process means your computer is standing by

Actually, I am having the same problem. AVG flashes a pop up that indicates RAM usage is around 250-300 and advises restarting IE, but ignoring it works out fine! There are several processes running, but looks like IE is using the most w/ 523K, and the System using 22K.

Thanks guys. Turns out that Google Chrome seemed to be my busiest program. But once I closed AVG, it seemed to be fine, dropping to around 12%. AVG did not find any viruses.

Can AVG be trusted?

Try a better antivirus. Microsoft Security Essentials is good and it's free. If you don't mind paying try Kaspersky or Eset.
