I don't know how it works, but I know the router is a physical barrier against viriea. Though the router isn't a full protection against outside trouble. I have a router (so does a friend of mine) and we regularly have encountered a hacker or virus inside the network (past the router).

That would be worms. The worms use ports and or protos that can be blocked by the firewall.
Virus files are filtered by Antivirus software based on bit count/headers/etc. Some high end firewalls can also run antivirus. But I never saw a home-use nat/router/firewall that could do anything with virus files and still allow normal traffic.
