Is it necessary to install anti-virus software after installing a firewall?

Firewalls and anti-virus software are two fundamentally different but complementary security application products. Firewalls are also known as packet filtering, essentially a software that monitors network traffic and attempts to enter and leave the network or compute all network traffic. A firewall is considered a screen or sieve that can filter potentially harmful data. Antivirus software looks for software that can compromise your computer programs, files, software, and more. It detects all unwanted programs, viruses, or infections that have been installed or are about to be installed on your system. It can perform a variety of protective measures, such as quarantine, permanent removal, repair, etc., to ensure that your computer is away from viruses or infections. In addition, it can scan or discover potentially harmful files that are downloaded from the Internet or attached to an email. Do you need antivirus software to install a firewall? The answer is needed. Firewalls do not protect your computer from viruses or other malicious software. It restricts the external network access to the computer or prevents local network access by restricting the port. This helps prevent your computer from communicating with other computers on your network on the Internet that you do not want. If you want to really protect your computer from potential threats, we recommend that you install firewall and antivirus on your computer, or at least enable the firewall on your router.
