What is the meaning of boot sector viruses?

Answer 1

A boot sector virus is a virus that's located in or directly modifies a special part of the hard disk in a computer called the boot sector. The boot sector, in basic terms, directs the computer to the things it needs to load the operating system and user interface so you can use it. Viruses that modify the boot sector can be loaded into memory at the same time or even before the operating system, and can prevent the computer from starting up correctly in some cases.

Boot sector viruses were more common during the days of DOS, when such viruses had easier access to the boot sector and other sensitive parts of the system. Today, these viruses are not very common because it is more difficult for them to spread and infect.

Answer 2

A boot sector is an area of your computer hard drive or disk that contains a program that starts the computer when it is first turned on.

You can get a boot virus from the internet or from a disk, which then effects your hard drive when the disk is inserted. The virus swaps itself for the program that boots your computer.

This type of virus can keep your computer from starting up when you turn it on.

Answer 3

A boot-sector virus takes control when the computer boots up and laces its own codes and commands into a computer's DOS boot sector.
