Is it necessary to install antivirus software after installing the firewall?

Firewall and antivirus software are two fundamentally different but complementary security applications.

Firewalls, also known as packet filtering, are basically software that monitors network traffic and attempts to enter and leave the network or calculate all network traffic. A firewall is considered a screen or screen that can filter potentially harmful data.

Antivirus software looks for software that can endanger your computer programs, files, software, etc. It can detect all harmful programs, viruses, or infections that have been 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 free from viruses or infections. In addition, it can scan or find potentially harmful files downloaded from the Internet or attached to e-mails.

Do you still need antivirus software after installing a firewall?

The answer is yes. Firewalls do not protect your computer from viruses or other malware. It restricts external network access to the computer or blocks local network access by restricting ports. This helps prevent your computer from communicating with other computers on the network on the Internet that you don't want.

If you really want to protect your computer from potential threats, we recommend that you install firewall and antivirus on your computer, or at least enable the firewall on the router.
