ccSvcHst.exe CPU hog in NIS 2010

I'm running Vista 32-bit, all up to date. Since installing NIS 2010 I've

had the dreaded "ccSvcHst.exe" problem, where 50% of the CPU

gets utilised.

 

3 times now I've uninstalled NIS 2010, run the removal tool, then

installed again. Sooner or later, sometimes on computer startup,

sometimes just on its own without warning, the CPU hog starts

all over again.

 

Has anyone solved this problem yet please ?
