Hello sorry for my incompleted question...it should have been.should I be worried

Firewall will control port and connect, it will protect your connection from outside and protect your port by default. There are cases that Malware would open a port from inside if infect your system. Then Anti-Virus could detect and remove and then close open ports by Malware.You may also restore Firewall to default to make everything normal in that case.
