Firewalls are an important component of computer security. The firewall is either a physical or software-based barrier that protects your computer from hackers, viruses and other malicious software. The Windows operating system includes a firewall that will protect your computer. As a default, the Windows firewall is turned on for protection. You can access different areas of your computer to determine which version of Windows firewall is running and ensure that the firewall is turned on and functioning.
Navigate to the "Start" menu and click on "Run," or place your cursor in the search box.
Type "Winver" into the "Run" box or the search box, and press the "Enter" key. This brings up the Windows Version in a dialog box. The Windows firewall that you're running corresponds to the version of Windows that you use. For example, Windows Vista is running a Windows Vista firewall.
Ensure that the firewall is turned on and protecting your computer by clicking on the "Start" button and then accessing the "Control Panel."
Search for "firewall" within the "Control Panel." The search brings up an option called "Windows Firewall."
Click on "Windows Firewall" to access the firewall menu. There is an option to turn the firewall on or off, click to turn the firewall on if it is not already on.
Tips & Warnings
- Have your administrator password handy in case you are prompted to enter the admin password when turning the firewall on or off.
- Within the firewall menu, check on the settings to ensure that the firewall is turned on for several network locations so that you computer is protected if you take the computer somewhere other than the normal environment.
- If you turn off the Windows firewall, your computer may be at risk for attacks, viruses, worms and other malicious software. To keep your computer secure, keep the firewall on and install a trusted antivirus program for continuous monitoring and scanning.
