I found the site about a month ago. I was surprised at what it could find out about my PC. I tried the Black Ice firewall he recommends. Now anyone trying to make an incoming connection can't even see my PC. Black Ice was another eye opener. I was amazed at the number of attempts to connect to my PC it has detected.
