Jack got an antivirus notification that an Apple TV that was trying to access his network. He said no, but it keeps requesting it. Leo says that if Jack has an Apple TV, it's probably trying to connect. It uses a utility called BONJOUR to connect. It's perfectly safe to talk to your mac. And since Jack has a router, his router is a perfect firewall to prevent outside connections. That's how he'll know it's the Apple TV that's trying to connect. So let it. And get rid of the AVS.
