A common type of virus is a boot virus, which is stored in the boot sectors of a floppy disk. If the
floppy disk is left in the drive when the computer is shut down and then turned on, the computer is
infected when it reads the boot sectors of the floppy disk expecting to find the operating system. If the
computer is infected, the boot virus may replicate itself onto all the floppy disks that are read or
written in that computer until the virus is eradicated.
