Okay thanks for your help. The person that wants to view the one program I can not trust to view the other files. So it best not to do anything like that. Right.
Correct. Setting up networks, enabling remote access and even using services like Go to my PC open holes (ports) on your network (router) Firewall and/or PC Firewall that make hacking into your system much easier.
A good secure Firewall is more important then your anti virus software.
