CCSVCHST.exe - high bandwidth usage

Lately I noticed my son's computer has been using a high amount of bandwidth.  I installed Netlimiter to see if I could pin point which program was creating the most usage.

 

When I looked at the log, it showed ccsvchst.exe used about 800 MB  1 hour & about 700 MB the next.

 

With Norton family installed & enabled for the main user account, would this be correct?
