                        ANTIVIRUS


                 A set of programs that identifies and removes malware is 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, AVG, McAfee, Quick Heal, Symantec, SmartDog,
                 Kaspersky, etc.
