Hi,

I reformated my pc last week and after installing Symantec antyvirus and
windows defender task manager sometimes it shows CPU usage of over 95% even
when wasn't running anything. I uninstalled both programs and it seem to have
fixed the problem.
But now there is a svchost.exe - application error. Instruction at
0x00b42740 referenced memory at 0x00b42740. the momory could not be written.
OK to terminate or CANCEL to debug the program.
I'm running Window XP Media Center Edition Version 2002 SP3
I don't know if these two issues are related or not.
Can anyone tell me where to find a fix for this problem?

Thanks
 
Back to the drawing board: The computer's infected again.

Back-up any personal data (none of which should be considered 100%
trustworthy at this point) then format the HDD & do a clean install of
Windows. Please note that a Repair Install (AKA in-place upgrade) will NOT
fix this!

HOW TO do a clean install of WinXP: See
http://michaelstevenstech.com/cleanxpinstall.html#steps and/or Method 1 in
http://support.microsoft.com/kb/978307

After the clean install, you'll have the equivalent of a "new computer" so
take care of everything on the following page before otherwise connecting
the machine to the internet or a local network (i.e., other computers) and
before using a flash drive or SDCard that isn't brand-new or hasn't been
freshly formatted:

Tip: After getting the computer fully-patched, download/install KB971029
manually: http://support.microsoft.com/kb/971029

NB: Any Norton or McAfee free-trial that came preinstalled on the computer
when you bought it will be reinstalled (but invalid) when Windows is
reinstalled. You MUST uninstall the free-trial and download/run the
appropriate removal tool before installing any updates, Windows Service
Packs or IE upgrades and before installing your new anti-virus application
(which will require WinXP SP3 to be installed).

If these procedures look too complex - and there is no shame in admitting
this isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA or Geek Squad) computer repair shop.

95% idle ? "Nothings running "
