When you connect your computer to the internet you open a gateway for a world of opportunities in cyberspace. Unfortunately, you also open a gateway for bad entities on the internet to come into your world.  These undesirables are out to capitalize on, or simply vandalize your valuable personal data, such as bank account numbers and passwords, your photos, documents and anything stored on your computer.

Hackers can also use your PC to attacks other computers, or networks ... without your knowledge.  They can even take control of your computer and lock you out!

A PC Firewall is your ally.  It is a full-time virtual wall that works in the background monitoring the ports and shutting the door on unauthorized traffic.

Any time you're connected to the internet you are a potential target.  As a result, whether you use dial-up, DSL, cable, or wireless a firewall is essential on the defense against hackers.

You can interact on different levels with your firewall to control access in and out of your system(s).

A bonus feature is that a firewall can hide your IP address from the world of the Internet, helping to prevent intruders from locating you.

Laptop owners should consider the likelihood of connecting to public or untrusted networks.  Having a firewall on your laptop can give you peace of mind in its protection.

*NOTE - while Windows XP Service Pack 2 contains a security suite including a firewall which has its benefits, there are threats that it simply will not protect you from.
