I dont know why but my computer's cpu usage is always 100%, and that slows down the computer alot! And in the task manager

I found out that Explorer.EXE is using 99% of the cpu most of the time, even when there isn't any program running! So I have to restart the computer everytime this happens, and it happens like 15 minutes after restart. Please help me!

I am using WinXp professional
PIII 1.0GHz
384mb SDram
GeForceFX 5200
30Gb Maxtor HD

Thank you

go to http://www.tomcoyote.org/hjt/ , and download 'Hijack This!'.
Unzip, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log somewhere, and please copy & paste its contents to the forum.

It will possibly show issues deserving our attention, but most of what it lists will be harmless or

even required, so do NOT fix anything yet.
Someone here will be happy to help you analyze the results.

I used Ad-aware 6 and removed some files, but Explorer.EXE continues to consume 99% of my cpu usage, and my cpu usage is again always 100%
