What is the error message you are seeing?
Why has Norton grayed out the controls for incoming PING? I cannot think of any reason why I would one an unknown entity pinging my system with permission.

Additionally, there are a couple of Windows incoming and outgoing controls the same way. Windows is the most hacked system in the world.

If you have any supporting screenshots, please add them:

Hello. Look to the top right and click “More” then create a new rule to block incoming ICMP.
