NIS 2012 and ccSvcHst

Hi, all. Occasionally getting four instances of ccSvcHst.exe*32 running. Two under System and two under Geoff, my computer user name. Is this normal, and what's occurring, apart from plenty of processor whirring noises ? It then reverts to two instances under Geoff, in the Task Manager.
