Why should I use a Firewall on my PC?

Firewalls are targeted at protecting your network from various threats coming from outside and trying to get in or threats coming from inside trying to get out. A threat does this by blocking network-enabled ports.

Every time a program tries to communicate through this port, the firewall verifies its database rules to check if it is allowed or not. If it doesn’t know, it will ask the user and that’s why you sometimes see a prompt asking you if a certain program is allowed or not to access the Internet.

A firewall is an essential issue regarding computing and every PC must have one installed. This is the reason why Windows has a firewall bundled and active as standard.

Windows firewalls must occasionally be told to allow a program to communicate with the network and this is the point where opening ports step into the picture.
