Should You Install and Use a Firewall Program?

If you spend any time on the internet other than just checking your email, then you probably do need a personal firewall.

A firewall is basically a software "shield" that stands between your computer and the internet. It is designed to block programs from entering or leaving your computer without your permission!

So what good does this do?

Hackers routinely use "robots" to scan cyberspace looking for vulnerable computers and networks.

A decent firewall automatically blocks or stops a robot from seeking entry to your computer. Like a castle wall prevents an attacking army from entering the courtyard.

And also like a castle wall, a firewall allows selected internal programs like Internet Explorer, etc, to access the internet. Using the castle concept again, a firewall allows you to control the "drawbridge" that lets programs come in or exit your PC.

A good program with both personal and professional version is "ZoneAlarm" at www.zonealarm.com. I have used ZoneAlarm for years and it has been a very stable program with a solid support system.

Another good application is the "Sunbelt Personal Firewall" (formerly known as Kerio). The Sunbelt/Kerio program was voted the best in 2006. It is a very strong system and very affordable.

Without programs like these, your computer is defenseless, and you are forced to use anti-virus and anti-spyware to clean up after the damage has been done by invasive software programs.

A firewall simply adds another layer of protection to your machine. And since you can only run one firewall on a PC at a time, I would recommend you try out the Sunbelt/Kerio first, although ZoneAlarm has a very nice "free for personal use" edition.
