the days unintentionally ran a virus without knowing it was bitdefender viruses and how viruses make connections know the issue is because the firewall does not prompt you IP address and port will make a certain unknown program without certificate? Ie even if it is a virus the bitdefender firewall should tell folder and the IP address and port where the program if you want to try to connect. It was good to prevent malicious people try to invade our system, something that the firewall does not.
