How to turn on your Windows Firewall (Seven, Vista and XP)

If your computer is being supported by Windows, then your computer also has a built in firewall. If your having virus problems, you might want to check to see that this firewall isĀ on if you don’t own a different firewall (such as Norton, Cisco, etc.). To check this, click the windows button in the bottom right corner, then in the search bar type Run. When the run window is open, type Firewall.cpl, and then click enter.

A screen should pop up like this one below.

If it says Windows Firewall is on, then your fine! For any reason, if its off and you want to turn it on click the Change Settings and change the setting from off to on.

So, why should my firewall be on?

A firewall checks information coming in from the internet and blocks it if it is unsafe. With your firewall off, this process is not happening. A firewall can help prevent hackers from gaining access to your computer, as well as helping to prevent viruses from spreading to your computer, or other computers.
