A firewall is a software program or piece of hardware that helps screen out hackers, viruses,
and worms that try to reach your computer over the Internet.
If you use a computer at home, the most effective and important first step you can take to
help protect your computer is to turn on a firewall.
If you have more than one computer connected in the home, or if you have a small-office
network, it is important to protect every computer.
You should have a hardware firewall (such as a router) to protect your network, but you
should also use a software firewall on each computer to help prevent the spread of a virus in
your network if one of the computers becomes infected.
