I recently had a firmware upgrade on my modem/router. The firewall picked up the network again, I had to re-allow sharing on the network on the PC's and re-allow incoming on ports 137 to get everything working. But my question is, I'm getting a firewall popup for application System unknown publisher and its trying to access outbound IPs 18.104.22.168 and 22.214.171.124. It keeps coming up and I'm not sure whether to allow it for good, or block it. Any help is appreciated!
