Please confirm it is the System and not System Idle process showing a
consistent 90%+ CPU usage. If it is System then you need to consider
whether problem is malware. Running Norton Internet Security is no
guarantee that you do not have a malware infestation. Some malware is
capable of concealing it's CPU usage.
I suggest you download and run Spybot S & D (freeware version). There
is a freeware version buried in this link:

Malwarebytes' Anti-Malware
1.32 -freeware (if you upgrade you pay).
http://www.download.com/Malwarebytes...-10804572.html
Run Malwarebytes' in safe mode and turn off your current anti-virus
before you do to avoid a conflict. Disregard the invitation on the web
site regarding the Registry Optimiser -a Registry Optimiser is not a
helpful utility.
Command line c:\WINDOWS\System32\svchost.exe -k imgsvc
What is your setting for Windows Image Acquisition? Start, Control
Panel, Administrative Tools, Services. Right
click on Windows Image Acquisition and select Properties. The default
setting is Manual.
Command line c:\WINDOWS\System32\svchost.exe - k LocalService
Have a look in the System and Application logs in Event Viewer for
Errors and Warnings and post copies here. Don't post any more than 48
hours ago.
You can access Event Viewer by selecting Start, Control Panel,
Administrative Tools, and Event Viewer. When researching the meaning
of the error, information regarding Event ID, Source and Description
are important.

A tip for posting copies of Error Reports! Run Event Viewer and double
click on the error you want to copy. In the window, which appears is a
button resembling two pages. Click the button and close Event
Viewer.Now start your message (email) and do a paste into the body of
the message. Make sure this is the first paste after exiting from
Event Viewer.
