As most of you are aware, security between your computer and the Internet is of utmost importance.
In order to assist you with making sure your computer is as secure as possible, here is a link to a website (Gibson Research) which will scan your Internet connection for any open holes through which malicious attacks may come.
Shields Up! is an online vulnerability scanner. It tests whether Windows is leaking information about you to the Web, whether your firewall is actually protecting you, and what websites see about you when you visit them.
I suggest that you click on each of the top row of tests, see what happens, and read what it says about the results. If it says you have passed entirely, feel good; if you get any other result, you should call me and I will come over and fix things up so that you will pass.
