    ANTIVIRUS SOFTWARE

                     An antivirus program detects the changes that a virus has caused in the computer. It is
                     recommended to install a good antivirus program to safeguard our computer from any

                     virus that may enter and update it consistently. Antivirus detects the presence of a virus,
                     warns us of the same and works to deactivate the malware.

                                       What if you could design an impenetrable cyber fortress to protect your
                                       computer from hackers? What features would it have and how would you
                                       use technology to build it?

                     FEATURES OF ANTIVIRUS
                     Antivirus programs contain an automatic update feature that prompts the user to update
                     the antivirus program from time to time because there are viruses being replicated every
                     day, hence, it is necessary to update the antivirus regularly to handle these threats.

                     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.
