I've been having trouble with my computer and I thought I cleaned it of all the viruses and such, however now it just runs extremely slow and I can't figure out why. I checked out my windows task manager and explorer.exe was using 99 CPU. When i closed it, everything worked perfectly and I had no problems (except i dont have my taskbar and desktop items). What is the problem here? I've run three seperate virus scans in safe mode, and they all say there is no adware, spyware or trojans... If anyone can give me some advice, I'd greatly appreciate it. Thanks.

Malware checks?

Virus scans are only part of the package...

Try using Process Explorer to see what is using explorer.exe when this problem occurs.

I downloaded process explorer and everything looked ok when explorer was turned off. When i turned it on, all that changed was that explorer was using more that 95 CPU at all times. Where should I go from here?

In Process Explorer right-click on explorer.exe and select properties and then click the Threads tab. See if you can identify the filename for the thread that is using +95% CPU.

One more thing - this type of behaviour is often caused by a malware infection. Have you run your scans recently?

it was a khheb.dll thread that was using all my CPU. I killed the thread, and it seems to be working much better now. What malware scan is the best to remove this kind of stuff? I already used a symantec scan, AVG scan and SpySweeper scan..

thanks

Try doing a scan with SuperAntiSpyware in safe mode. Let us know how it goes.

Here's our guide for it's removal: http://www.bleepingcomputer.com/forums/t/47826/how-to-remove-spywarequaked-and-spywarequake-removal-instructions/

If SuperAntiSpyware doesn't fix it, then I'd suggest a visit to these forums:
