                    In 1986, the first virus was written for Windows based PCs by two brothers, Basit and Amjad
                    Farooq Alvi, from Pakistan, who were only 17 and 24 years old at the time. They named it “Brain”.





                      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.

                           #Survey

                   Conduct a survey of at least 10 homes in your colony/society. Ask which antivirus is installed on
                   their computer system/laptop and note their names. Is there any computer system/laptop that
                   doesn't have any antivirus software? Make a record on chart paper.
