The kids and I have been playing Minecraft together for a year or so on our home network with no problems. For Christmas we got them new laptops to play on, now whenever they open a world to LAN I get Symantec Port Scan attack popups on my computer and it blocks their laptop. It only happens when they play Minecraft. Any ideas?
When you start a LAN game, it uses a random port for connection purposes. Your antivirus software detects this as malicious, hence blocking the connection.
We do not recommend Symantec products as they cause more trouble and harm than good. Please consider using a better alternative such as avast!
