Windows Firewall is a built-in protection tool that safeguards inbound and outbound traffic on a network. Depending on computer’s configuration, Windows Firewall may block or let pass any information. Firewall is very essential to prevent malicious software, Trojans and viruses from gaining access to your system whether the request originates from local network or the Internet. Preventing hacker’s attack from stealing sensitive data from your computer is also feasible with the proper implementation of Windows Firewall. It stops the system from sending confidential data and other sensitive information to a remote computer.
Firewall is very much different from antivirus programs. Firewall will guard and screen malicious network traffic and not the files that pass through it. While, antivirus software is the one responsible for preventing harmful files getting in to the system.
