                  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.
