Mystery process takes 50% of CPU time

Specs: Windows XP, 512
I have a PC that has a mystery process that is taking around 45 - 50% of CPU resource on Win XP SP3

When I look at the processes in task manager, everything shows around 0%, but the main % indicator at the bottom of task manager shows around half of the CPU time is being used - and I believe it because the PC is noticably slow.

Hence, it would seem to be an invisible process.

So far I've done a scan for Viruses, Malware, Spyware, Adware. Plus I've run sfc /scannow. I've also stopped all extra tasks starting up using msconfig - no difference.

A mystery!

Older Computer running XP?

Would help if you identified your System and supply particulars.

There is nothing to learn from someone who already agrees with you.

More than likely your task manager window is minimized so as to not show all the processes going on in a single window. expand the window and then see what the process is doing it.

It could be a spyware or back up application doing what it is suppose to do.

Most Virus and Spyware scans are likely to work better in Windows Safe-Mode.

To find out what each Startup(or Process) item
does or means, and any recommendation as to if you should close the process:

I found the problem. It turned out to be the Google Toolbar Notifier.

It was "Security Task Manager" that highlighted it as a potential problem. I then uninstalled it and the extra CPU overhead disappeared.

Still can't understand why Task Manager didn't show up with the related process - it was totally invisible in the process list.
