What does your Windows firewall do?

Sadly, the Windows firewall does very little, if anything, to help protect your computer.

Of the 25 recognized firewall tests - Windows firewall passed none.

Think of a firewall as having a security guard on every door and window of your home. That security guard only lets the people you allow to enter or leave.

It is a good idea to have a firewall, just it is not a good idea to depend on the Windows firewall, there are much better free ones available on the internet.
