How has DefenseWall 3 beta been working on your machine. I started using DefenseWall in April 2009 (now using v2.56) and have been extremely happy with it. It is one of those programs that you wonder how you ever did without. Is the firewall in v3 something that is automatically installed and if you don't need it you disable it or do you have a choice when installing the new version on whether to install the firewall portion? Also, how does the firewall work. Is it an application permission type firewall?
