In this video, Mahalo computer expert Sean Hewitt explains what you need to know about firewalls.

What Is a Firewall?
---------------------------------------------------------------------

Firewalls block or allow internet activity on your network. They are an important protection to use when browsing the internet with your computer. In addition to a software firewall installed on your computer, your router probably has a form of firewall as well for added security.

Manage Your Firewall
---------------------------------------------------------------------

Windows 7 comes with a software firewall installed on it. To manage it: 
Go to the Start menu.2. Click on Control Panel.
3. Go to System and Security.
4. Click on Windows Firewall.  
5. Make sure your firewall is set to "On."
6. If you want to allow certain programs through the firewall, click on "Allow a program or feature through Windows Firewall."
7. Click "Change settings" and update information to allow or deny access through the firewall.

If you're not using Windows 7 but still have a Windows computer, you can use a third party software firewall. Sean suggests downloading the free firewall from ZoneAlarm.
