Boot sector virus (2) macro virus​

Answer 1

Explanation:

A boot sector virus usually infects the computer by altering the boot sector program. The virus replaces the default program with its own corrupted version. A boot sector virus is able to infect a computer only if the virus is used to boot up the computer. The computer will not be infected if the virus is introduced after the boot-up process or when the computer is running the OS.
