SUMMARY
Boot-sector viruses infect computer systems by copying code either to the
boot sector on a floppy disk or the partition table on a hard disk. During
startup, the virus is loaded into memory. Once in memory, the virus will
infect any non-infected disks accessed by the system. Examples of boot-
sector viruses are Michelangelo and Stoned.
