Most antivirus programs automatically check for viruses when they are installed. They
                  also automatically scan all the downloaded files from the Internet, e-mail attachments,
                  and all types of removable media inserted in the computer.


                  WORKING OF ANTIVIRUS
                  An antivirus program scans all the files and when an infected file is identified, it tries to

                  remove the malware. In case it fails to remove the infection, it quarantines the infected file.
