I need to do something to protect my sometimes/ex/girlfriend's Windows PC. Can't go into why she needs a Windows machine, and that may change eventually, but I need to set up some protection for her on her home broadband connection, something that I can (eventually) manage and admin remotely. I am not really a Linux user myself, but I'm learning. My plan is to go (almost) 100% Linux in the near future. So for my girlfriend... What I'm thinking is a separate Linux box as a network server. Can anyone sketch-in some of the basics for me?
