What is a Firewall ?
A firewall uses a wall (of code) that examines data as it arrives and/or
leaves your computer, then determines whether it should be allowed to
proceed. It is not the same as antivirus software.

Firewall software

Today, home or small business computer offers numerous opportunities for
attacks especially now with wifi wireless network connections. Many home
computers store important information like credit card numbers, bank and
brokerage account numbers. Because most home computers have little or
no security, they become easy prey for hacker attacks.

Expanding the problem is the increase of always on connections to the
Internet, such as DSL, cable modems, and LAN systems that makes it easier
for your computer to be broken into.

When you are connected to the Internet, an IP address is used to identify your
PC and that IP address can be used to access your computer from the outside
world.

If you have a DSL, cable or a constance connection you have a fixed IP
address, you give potential Internet hackers all the time they need to
search for entrances to your computer and eventually take data, use your
computer to hack into somewhere else and even destroy your pc.
