gamed process blocking-firewall

gamed was stopped from accessing the internet and a popup showed up deciding whether to allow, however, the popup disappeared and I was unable to make my choice. I found the process on the hard drive but am unable to browse to the full path of its location in Norton to manually block the process from making another attempt.

/System/Library/PrivateFrameworks/GameCenterFoundation.framework/Versions/A/gamed is the full path of the process but I cannot get into the GameCenterFoundation.framework folder from Norton Security. Is there a command line to add this process to the blocked list?
