                ANTIVIRUS

            A set of programs that identify and remove malware are
            known  as antivirus  software.  You  must have  an  antivirus

            software installed on your computer. It detects the virus in
            the computer and does not let the virus copy itself on your
            computer system.

            Hundreds of new viruses are developed every hour. Antivirus
            software developers regularly release updates on the

            Internet that allow their programs to detect the latest known
            viruses. You can update your copy of antivirus only through
            the Internet. So, it is essential to have an Internet connection
            to update antivirus software.

            Some well-known antivirus programs are Norton, Quick Heal, AVG, McAfee, Symantec, Kaspersky,

            etc.

                FIREWALL

            The term ‘firewall’ originally referred to a wall intended to confine a fire or potential fire within
            a building. In computer, a firewall is a software or hardware-based network security system that

            controls the incoming and outgoing network traffic based on applied rule set. A firewall acts like
            a gatekeeper and prevents unauthorised access to a computer network.
