Can virus spread through floppy disk?
Boot sector computer viruses are most commonly spread using physical media. An infected floppy disk or USB drive connected to a computer will transfer when the drive’s VBR is read, then modify or replace the existing boot code.
What is boot sector virus?
Boot sector viruses infect the boot sector or the partition table of a disk. Once a computer is infected, boot sector viruses usually attempt to infect every disk accessed on the infected system. In general, boot sector viruses can be successfully removed.
Which virus attaches itself to the boot sector of the disk?
A boot sector virus is a type of virus that infects the boot sector of floppy disks or the Master Boot Record (MBR) of hard disks (some infect the boot sector of the hard disk instead of the MBR).
Which virus spreads through the floppy disk all over the world?
Elk Cloner
Elk Cloner is one of the first known microcomputer viruses that spread “in the wild”, i.e., outside the computer system or laboratory in which it was written. It attached itself to the Apple II operating system and spread by floppy disk….Elk Cloner.

What does a floppy disk contains?
A floppy disk or floppy diskette (sometimes casually referred to as a floppy or diskette) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk.
What is the example of boot sector virus?
Some common boot sector viruses include Monkey, NYB (also known as B1), Stoned, and Form.
Is an example of boot virus?
In most cases, it takes bootable antivirus disks such as a Symantec/Norton AntiVirus (SAV/NAV) rescue set to properly remove a boot sector virus. Some common boot sector viruses include Monkey, NYB (also known as B1), Stoned, and Form.

What is the definition of boot sector virus?
– Definition. A boot sector virus is a type of virus that infects the boot sector of floppy disks or the Master Boot Record (MBR) of hard disks (some infect the boot sector of the hard disk instead of the MBR). The infected code runs when the system is booted from an infected disk, but once loaded it will infect other…
Can a floppy pick up a boot sector virus?
In most cases, all write-enabled floppies used on an infected PC will themselves pick up the boot sector virus. In the past, setting the computer to boot first from the C: (hard) drive and then the A: (floppy) drive, or never to boot from the A: drive at all, was a reasonable precaution against boot sector viruses.
Can a boot virus spread from one disk to another?
From memory, the boot virus can spread to every disk that the system reads. Boot sector viruses are typically very difficult to remove, as most antivirus programs cannot clean the MBR while Windows is running.
How does a virus spread from one floppy disk to another?
The infected code runs when the system starts from an infected disk, but once loaded it will infect other floppy disks when accessed inside the infected computer. While these viruses infect at a BIOS level, they use DOS commands to spread to other floppy disks.
