    ANTIVIRUS

                  A security program designed to prevent, detect, search and remove malware from computers 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
                  anti-virus 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.

                     system/laptop that doesn't have any antivirus software? Make a record in an excel sheet.
