ccsvchst.exe problem

 

Windows 7 machine with very little additional software.

I am having a problem with almost continuous (50%) CPU usage by a program named ccsvchst.exe.  This does not occur when the computer is switched on but not connected to the Internet.  Once the machine is connected to the Internet the programme starts and it continues running even if I break the Internet connection.  A Norton warning called “File Insight” came up with the report written in red “100% of at least one CPU”.  This seems to be way beyond just updating which has always worked well.

What can I do to stop this?  It’s clearly using a lot of my computer’s resource and it results in the processor running hot so the cooling fan runs all the time.
