This next part of the series I will highlight two software firewalls. Having one of these installed on your computer will definitely add a much-needed layer of protection while you’re connected to the Internet. But first I’ll briefly describe what a firewall does.

Basically, a firewall monitors the data traffic that your computer sends and receives. For example, when you visit a Web site, your computer and the site you’re on exchange information on how to display the Web page. Based on its instructions, the firewall decides whether it should send or receive that information. So, it’s an extra line of defense between you and the rest of the Internet.

There are two types of firewalls: hardware and software. Having both is better, but one is good. I’m going to talk about the software kind.

Windows Built-in Firewall
This is something Microsoft offers as part of its operating system. In addition to it offering a firewall, it automaticlaly checks for updates to the operating system, and provides virus protection. It’s a good way to protect your computer if you have absolutely nothing else to do the job.

To check if you have it or to set it up, click on Start > Control Panel > Security Center. This will bring up the window allowing you to configure your settings for three features. If you already have a firewall installed (like one of the ones I’m about to talk about), then I think it’s a good idea to turn off this built-in solution. Why? It’s not a good idea to have more than one of anything running at the same time. This holds true for antivirus software, too.

Kerio Personal Firewall
Sygate’s free personal firewall was going to be my next choice, but then I remembered them being bought out by the behemoth that is Symantec. Once they did that, they discontinued Sygate’s consumer products. (Note: if you’re desperate, and you have a lot of patience, then go ahead and use their products, but I have heard and experienced more negative things about their products than I have positive.)

So I moved down the list to Kerio. They’ve been bought by Sunbelt Software. Never heard of them, but I hope they don’t muck things up. Their Kerio Personal Firewall is still free, so download it now before they change their minds!

I wish I could tell you more about Kerio, but seeing as how I’ve been pleased with Sygate’s now-discontinued product, I never had the need. However, with Symantec gobbling up the little guy and with Kerio providing a free alternative, then I just might have to at some point.
