The firewall in networking is a secured wall between public and the private network. It protects your internal network from the user of an external network. The firewall may consist of hardware or software or both. They work by collecting related packets until the connection state can be determined before any firewall rules are applied to the traffic.

Firewall is for protection from threats from network, whereas anti-virus works against virus on the local machine where it is installed by scanning everything which is installed or running.
