Update the Antivirus

                 If some new virus has developed after the installation of the previously loaded antivirus, then it may not
                 be recognized by the loaded antivirus and therefore it may not detect that virus. In that case the existing
                 antivirus has to be updated in order to install its latest virus signature & clean new virus. For updating an
                 antivirus, the user needs to connect to its URL, the antivirus would automatically get updated on the host
                 computer.
