Will do. I'll let you know how things go.
Thanks for your help.

Boot to safe mode and do a Virus scan.
Next: Rootkit detection software is just another flavor of Stealth Virus
detection, so find a free version that you can download, install and run.

Thanks again JS.
Before I get into rootkit stuff (looks complicated), a few more clues and
details.
1) I have Norton Anti-Virus completely up-to-date (includes spyware)
2) I have ZoneAlarm Pro completely up-to-date (includes spyware)
3) I have PestPatrol completely up to date
4) The System process doe not exhibit the 50% CPU time when I boot in
Safe Mode with networking
5) When I use MSCONFIG and stop everything I can and reboot, the sytem
comes up again and pauses at the MSCONFIG screen. At this point the task
manager and ProcessExplorer show very few processes but the System
process still shows 50%
Any comments on this?
Kind regards,
Vic

If it's the System process and not a sub-process underneath it as your
attachment shows then it could well be a rootkit (stealth virus).

Thanks for that JS
It is the System process itself that is using 50% of the processing
time.
Expanding the Process Tree shows that there is nothing much underneith
System which is using any time at all. It is something internal to
Microsoft's System process. I wonder if anything has corrupted System!
I have attached a view of the Process Explorer screen if this may help
shed
any light on the problem.
Any further ideas?
Kind regards,
Vic

You need to find the specific process in that application that's
taking
all
the CPU resources.
To do this try Process Explorer:
http://www.sysinternals.com/Utilities/ProcessExplorer.html
Once you have Process Explorer installed and running:
Click on the CPU column to sort processes by %CPU usage.
Then click on the process that using most or all the CPU %, once it
highlighted, right click
and from the options listed select: google
This should display what out there on the web about that process.
Note: some entries like svchost may need to be expanded to show the
detail,
in this case click on the + located to the left on the entry.

Hi,
I have XP SP2 -completely up-to-date I think - and the System process
is
taking over 50% of the CPU time - all the time! Any ideas how to
track
down the cause of the problem. It's a bit tricky when it is the main
Windows process that seems to be causing the problem!
Regards,
Vic Russell
