2 Questions about Norton

Hi I have Norton Internet Security 2010 version 17.5.0.127 installed and have two questions.

 

1) When I leave my computer on and it goes on to screensaver mode and I come back I see that the Norton main program is open and it's minimized, why is that?

 

2) What do "ccproxy.exe" and 2 "ccsvchst"'s exactly do?
