when to act as server

I am confused on when I should let a program act as server. Also if I leave everything as it is installed will I be protected?


The default settings will protect you as you are.

For apps acting as a server the following post gives plenty of detail about this type of alert:


Is there any way to list the various files that have been granted permission for “acting as a server” etc. and how to change them? In addition, can a file be limited to “act as a client” and is that more or less “liberal” than acting as a server?

When the program is not a proxy server. It’s the loopback check that’s causing the alerts: https://forums.comodo.com/index.php/topic,6591.0.html
