Once you connect your computer to a local network or to internet, you are automatically exposed to some security risks. Your computer can be found by others through the network or internet and they can try to access to your PC. Or you can install a virus that can send information from your computer to third parties.

To control incoming and outgoing connections and keep your computer safe, you must use a firewall. This is different from antivirus software, but often a firewall application may be included in an antivirus product (often called Internet Security Suite).

A firewall is like a gate/door of your house: you control who comes in or exit. A firewall will keep away thefts to use your computer (people from outside or viruses from inside of your PC).

You can use separate programs for firewall and for antivirus. The advantage of using a separate firewall is that they offer, usually, a higher level of customizations and control for setting block rules, close ports etc. Also, Windows usually have a default firewall application included and if you use a router for network/internet access, these routers usually have a firewall included, too.

Here is a list with 4 best free firewall software.
