I have Norton antivirus and firewall 2004, and when I check to see what ports are opened these two always come up listening.

ccProxy.exe 1025 LISTEN TCP C:\Program Files\Common Files\Symantec Shared\ccProxy.exe
ccApp.exe 1029 LISTEN TCP C:\Program Files\Common Files\Symantec Shared\ccApp.exe

I was just wondering if Norton has to have ports open all the time. If so do they have to be listening on these ports or can I change what ports they listen to. By the way i run on windows xp home. Thx
