Hi, I have an XP machine that has 100% CPU usage all the
time.
The main problem seems to be with svchost taking up 50%
to 70% of processing time.
The knowledge base talks of this problem it windows 2000
server but not XP.
There are other funny things happening as well. When you
are running REGEDIT it closes automatically after a few
seconds, and Nortons is also blocked.
It sounds like you have picked up a virus that immediately breaks any av
installed. This could happen if you had an older NAV version, weren't
updating its definitions or didn't renew your subscription. Without more
details about the NAV you have installed, I can't be more specific. The
usual way to deal with this (if this is applicable to you) is to:
1) Take the infected machine off the Internet and any lan immediately.
2) From a different, clean machine download Stinger from here:
http://vil.nai.com/vil/stinger/ and run it in Safe Mode. Stinger is a
limited virus checker, but it's advantage is that it is standalone and
doesn't need to be installed.
3) Hope that Stinger cleans up the machine enough to be able to
reinstall your av or install a new, current one. Update its definitions
and do a full scan.
4) Continue the cleaning process by removing any spyware with Spybot
Search & Destroy from
www.safer-networking.org and Ad-aware from
www.lavasoftusa.com. Be sure to update these programs before running
them. These programs are free, so run them both since they complement
each other. It is best to run antivirus and spyware removal tools in
Safe Mode.
If you need more help, then please repost with details about your av and
anything else you think will be helpful to give a good picture of your
situation.
