Firewall indicators are important to administrators and computer users so that they can know they are secure from network attacks.

By default, Windows firewall is proactive and it is up to you to set your ideal settings and to fine-tune the kind of notifications that you wish to have for your network profiles such as Work, Public and Home. Note that while the protection offered by the Windows firewall is minimal, it is still very important. You cannot afford to do away with it. Even when antivirus programs tell you to turn it off, do not turn the firewall off.

If you have a house, you can relate it to the importance of locking the front door to bar intruders and thieves from entering your home. That is the same case with a firewall; it bars malicious software and hackers from invading your PC.

How can firewall protect you?

Every computer user today is concerned about spyware and viruses. Each of these two can pose a problem and the only way to curb them is by being proactive. For starters, it is always advisable to update your software as well as install the necessary patches. Your operating system should also be updated regularly.

Here are other factors that will curb any malicious software and hackers:

  • Install antivirus and antispyware software and update them regularly.

  • The firewall cannot do all the work on its own. Thus, you will need to use a good antivirus program that can alert you when you are about to access an infected website.

  • Do not open unfamiliar email attachments when you are not sure about their source. Delete them right away.

Why it is important to keep the firewall running

When your PC is linked to a public network, say, like the public Wi-Fi at your favorite coffee shop or your local library, your PC safety is not assured; however, a firewall will block such incoming connections.

The Windows firewall gives you the freedom to choose the ideal protection level for your various profiles and to manage them easily.
