                      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.
