How well does your firewall work for you?

Do you even have a firewall set up? Some just fail to realize that having pc security is necessary in this digital era. There are people out there who would love to dig through your files just for fun. Some have thought that using the firewall that somes standard w/an operating system like Windows XP is enough. Others go a step further and use a 3rd party firewall for added protection. First, try to scan your pc and see if it's open to attack.

You can go to Hackerwatch to scan your pc which will test your firewall, or there are other links you may use to scan/test your firewall.
