For some reason, the process ccsvchst.exe uses 25% of my CPU for a period of 25-30 minutes before stopping. This doesn't seem normal to me and would like to get some of your thoughts about possible fixes (if any).
After some head scratching, I was able to replicate this problem by doing the following:
1) go to Avast's website
2) download the Avast antivirus program onto my desktop
3) NIS 2012 displays message that the file is clean and stable
4) After NIS 2012 displays message, ccsvchst.exe runs at 25% of CPU for about 30 minutes and then it stops
(I also noticed that I could stop ccsvchst.exe by simply rebooting.)
Thinking it was a NIS 2012 bug, I uninstalled NIS 2012, using Norton's removal tool, and reinstalled NIS 2011. I repeated the above procedure using the freshly installed NIS 2011 (I did not run Live Update) and did not have any issues (ie ccsvchst.exe did not hog the CPU at all!!). I then updated NIS 2011 using LiveUpdate, repeated the above procedure and the problem returned ( ie ccsvchst.exe showed 25% CPU loaded that lasted for about 30 minutes or until I rebooted).
So, both NIS2011 and NIS2012 appear to have the same issue with high CPU loading.
My system: Win 7 (64 bit), Quad Core CPU, 4GB RAM, no other antivirus programs installed
Thanks in advance for any advice.
