Block access for a program

You can block a program from having incoming and outgoing Internet access. This is an important option for users who want full control of their PCs, allowing access only for the programs they trust, and blocking everything else.

Ensure that blocking a program does not interrupt your network connection or any other program that requires Internet access to function properly. Certain programs, like web browsers, need access to the Internet to function.
