Question

Differentiate between boot sector viruses and file infecting viruses?​

Answer 1

Answer:

.Boot sector viruses

• The boot sector virus is a computer virus that infects a storage device's master boot record (MBR) of hard disks. During start-up, the infected code runs when the system is booted and gets loaded to the computer's memory, however, once loaded it will infect other floppy disks when accessed in the infected computer.

.File infecting viruses

• A file infector virus is a type of virus that typically attaches to executable code, such as computer games and word processors. Once the virus has infected a file, it can spread to other programs, and even into other networks that utilize the infected files and programs.

Answer 2

Answer:

Boot sector is a region in a secondary storage device such as a hard disk or a CD where the instructions to load the programs stored on the device are coded. These instructions are read during booting.

Boot virus targets the boot sector of secondary storage devices by copying itself to the existing code. A hard disk, pen drive or an external hard disk gets infected in the process.

A file infector virus is a type of virus that typically attaches to executable code, such as computer games and word processors. Once the virus has infected a file, it can spread to other programs, and even into other networks that utilize the infected files and programs.
