Windows Firewall

How good does Windows Firewall work to protect your computer from getting viruses when surfing the web?

For most home internet users, your router acts as a pretty good firewall so generally Windows doesn’t have much work to do. But if you plug straight into a modem or use public hotspots, Windows firewall generally does quite a good job at stopping stuff connecting when it shouldn’t. I’m not aware of any advantages gained by using a third party firewall vs the one that’s built into windows!
