Question on ccSvcHst.exe using 99% of CPU

Like other people I have been having a problem with ccSvcHst.exe using basically all of my cpu. For some reason I have two ccSvcHst processes runnning, one under the username System, the other on under my username. Because of this I suspect my problem might be as described below.

One member suggested here "If you are using NIS 2009 ONLY, then please go to Windows Add-Remove Programs and check if you see Symantec LIve Update and / or Live Update Notifier. These items are not needed by NIS 2009 and if present should be uninstalled; but uninstall ONLY if you use NO OTHER NORTON PRODUCTS."

I checked Windows Add-Remove Programs and itsays I have LiveUpdate 3.2 installed, and LiveUpdate Notice installed. Are either of these safe to remove if I am only running NIS 2009?

Hi jasimp,


Welcome to Norton Community!


Since you have LiveUpdate 3.2 and LiveUpdate Notice in Add/remove Programs, this can be remnants from the previous version you used. That may be the reason of for the high CPU usage. It will be better to use Norton Removal tool for uninstalling Norton 2009 along with all those remnants and then reinstall NIS 2009. Here are the necessary steps:

1. Go to your Norton Account using this LINK and get the Product Key of 2009 version. You may require this same Product Key for activating the Norton 2009 program.

2. Download the Norton Internet Security 2009 16.5 version from this LINK, don't install it now.

3. Download and run Norton Removal Tool from this LINK. Run it multiple times(2-3 times) to make sure that all the previous components are removed completely. You may need to restart the computer whenever you run Norton Removal tool.

4. Now install Norton 2009 and activate it using the same Product key.

The ccsvchst.exe file is automatically added to your computer upon installing the Norton software, and it is referred to as the Symantec Service Framework. The ccsvchst.exe file works to display the GUI (Graphical User Interface) of Norton products, which usually include the Norton Security Suites. Getting two ccsvchst processes is perfectly normal.  One of those ccSvcHst.exe processes should be running as the SYSTEM user and one should be running as the currently logged in user ("Tom" or "Administrator" for instance). Basic explanation is that the one running under the logged in user is responsible for showing you the UI and allowing you to interact.  The process running as SYSTEM is the service that does all the actual work (determining idle time, running scans, etc.).
