You got anti virus? Done a scan?

Whats your explorer.exe cpu usage when idling in windows for a couple mins?

Yeah, that sounds like some malicious action. What AV software are you running?

I am using Kapersky Internet Security 2010

Just dumb question (maybe) but do you have a USB based soundcard on your system >?
The answer will make me explain my theory..

Tried a Windows repair? Maybe your explorer.exe got hijacked without Kaspersky picking it up.

right click explore.exe and go to the directory it in. scan it and see what it does? check you process list for suspicious processes and do the same. if you find one called sys.exe you have a recycler virus/worm

You could also try and copy an original Explorer.exe over the current one using a Linux Live CD or try to use the Windows Repair Console.
Just watch the version you copy make sure the same SP is applied.

Thanx.When I get home today I will see if the problem can be fixed by your suggestions.I dont have an active internet connection at home I use my N73 as a modem so Kapersky hasnt been updated since I bought it.I just downloaded windows defender's latest definition at work.I know some people says that windows defender is crap but it is worth a try don't you think
