Rundll32.exe occupies CPU upto 100%

[Guest]

My notebook recently runs very slowly and I identified from Task Manager that rundll32.exe occupies CPU upto 100%. I have already run Norton Utilities, Ad-aware and Spy Hunter but the problem still persists. Can anyone tell me what I have to do next?

Have you used scanned your computer with Norton AntiVirus for viruses?

Yes, I have scanned my notebook with Norton Anti-Virus 2003 (already updated) thoroughly and there was no report of virus.

I have the same problem. When I end the process through Task Manager, computer gets sort of freed and come back to normal speed. RUNDLL32 gets activated only when I wanna play a video game! I located the file, though cannot delete or move it to another place so it stops slowing.
