What is Boot Sector Virus ?
by

1 Answer

Answer :

: The first sector of the floppy disk is the boot sector. The boot sector of the hard disk is the first sector of the partition. It contains information about disks or partitions ; For example, the number of sectors. It also has six programs. When the computer is turned on, it first tries to read the boot sector of the A: drive. If it cannot, that is, the drive does not have a disk, then it reads the boot sector of the C: drive. The boot sector virus replaces its own code in this sector and transfers the original disk to another location. A: If there is a non-bootable disk in the drive, then the computer turns on and tries to boot from this disk and displays the message "aenot Bootable" on the screen . Therefore, if a non-bootable disk contains a virus, it can easily infect the computer if there is a disk on the drive when the computer starts.
