Antivirus software are the utility programs that detect and prevent your computer system from attack of viruses. The main task of an antivirus software is to check all the programs/data files available in the computer. If a virus is detected, the antivirus clears it from the system. A pirated antivirus software should not be used because it will not be able to remove all the viruses, rather it may spread the virus itself. So, you are advised to install original antivirus software and keep it updating periodically. The updated antivirus software also takes care of newly created viruses.

(a) Which of the following statements is not true about antivirus software?

1. It locates infected files.

3. Once installed, it needs not be updated.
4. It removes viruses.
