Do you have Norton Internet Security (NIS) installed?
If you are, running 2 firewalls is NOT recommended. Please uninstall one of them. I'm surprised you're not experiencing more conflicts!
About ccProxy.exe: click here. What you'd like to check is whether it's running from the folder in the link. If you don't have NIS installed (or never have) then it could be spyware/trojan/etc & must be removed. G
