In Computer science as “Firewall” we mean a software program or a hardware network security device that controls the network traffic. In other words, a “Firewall” prevents external attackers to access our computers and our network and keeps us more secure.
Windows Firewall is a software security program designed and offered by Microsoft in its latest Operating Systems. Windows Firewall feature is enabled by default after Windows XP Service Pack 2 (SP2) is installed and it helps Windows users to control the network traffic from/to their computers. For that reason, many malware programs (viruses) may compromise the Firewall settings to make your computer insecure from external attacks or to block your network connectivity.
In this tutorial, I will guide you on how to restore the Windows Firewall settings to their defaults.
