High CPU usage with no underlying process to be found!

[Admor]

I have this very scary situation when suddenly everything is going so sloooow.
I close every application, then I open Task Manager, hit "Show processes form all users", and it says: System Idle Process: 98%, CPU Usage: 40%, Memory Usage: 40%
I scan all the processes. they are all "quiet". must be a hidden process!
I even used YAPM, which supposed to show any hidden process - and nothing!
First time it happend, I used System Restore and it seemed to go away. But it keeps happening!

 

Is this a "known" issue?

Please HELP!

Hello and welcome to Computer Hope Forum. My name is Dave. I will be helping you out with your particular problem on your computer.

1. I will be working on your Malware issues. This may or may not solve other issues you have with your machine.
2. The fixes are specific to your problem and should only be used for this issue on this machine.
3. If you don't know or understand something, please don't hesitate to ask.
4. Please DO NOT run any other tools or scans while I am helping you.
5. It is important that you reply to this thread. Do not start a new topic.
6. Your security programs may give warnings for some of the tools I will ask you to use. Be assured, any links I give are safe.
7. Absence of symptoms does not mean that everything is clear.

If you can't access the internet with your infected computer you will have to download and transfer any programs to the computer you're using now and transfer them to the infected computer with a CD-RW or a USB storage device. I prefer a CD because a storage device can get infected. If you use a storage device hold the shift key down while inserting the USB storage device for about 10 secs. You will also have to transfer the logs you receive back to the good computer using the same method until we can get the computer back on-line.
