Question

What type of virus first infects files and then works as a boot sector virus? It ultimately changes the Master Boot Record (MBR) of the hard disk. Once the boot sector is infected, the virus loads into memory and begins to infect all the program files.

Option 1: Boot-sector
Option 2: Multipartite
Option 3: Stealth
Option 4: None of the above

Answer 1

The virus that infects both files and the boot sector, ultimately altering the MBR, is known as a multipartite virus.

Step-by-step explanation:

The type of virus described in the question that first infects files and then operates as a boot sector virus, ultimately changing the Master Boot Record (MBR) of a hard disk is known as a multipartite virus. This virus is designed to execute multiple types of infections at once; it is capable of infecting both executable files and the boot sector. With the ability to load into memory on system start-up, it can continue to infect files while the system is running.
