I'm setting up a windows machine for a friend and wanted to install a free firewall. The trick is, I need the firewall to be interactive in that if a program requests to get 'out' the firewall gives an alert and the chance to block all external connections for the given program (and remembers the choice).
The last time I was on windows I used a firewall that seemed to grant access to programs willy nilly which was incredibly frustrating.
Does anyone know of such a program for windows (vista)?
