What does “allowing a program through the firewall” mean?

Hi Nrodztrisk,

Basically firewall blocks unidentified programs in your computer, which usually comes from the internet.  Because sometimes when you surf the net unidentified programs comes into your computer, like for example a virus.  Both are examples of unidentified programs.  But there are also programs which are still alien to the computer that we install, which are also brought by the firewall, because again the computer is not familiar with that program. That is why the firewall blocks it.  Also that is why the firewall has a setting which is also called exception, so that we can lift the program we want to install that will not be blocked by the firewall.

Basically, when we include the program in the list of exceptions, your firewall will not block that specific program.
