I notice my computer had started slowing down. Using SysInternals Process Explorer I found that ccsvchst.exe for Symantec Service Framework is consistently using between 95% and 98% of my CPU time. Specifically this is running using the Norton Internet Security (NIS) service. The path is C:\Program Files\Norton Internet Security\Engine\\ccSvcHst.exe. I ran Malwarebytes, but it found nothing.

Does anyone know what the problem is and how to fix it?

Seems to be a common issue if you take a look at the http://community.norton.com website.

Seems to be a recurring starting point for troubleshooting.

If you do a Google Search, you will find this is a common complaint from Symantec users over the years who have posted about it many times in the Norton Support forums and elsewhere.

I have yet to find an official explanation of the ccSvcHst.exe high cpu usage from Norton as there seems to be various causes and solutions so they probably feel it is better to deal with the issue on a case by case basis.
