Subject : Boot Sector Viruses Boot Sector Viruses Boot sector viruses reside in the part of the disk that is read into memory and executed when your computer first boots up. (On a floppy disk, that’s the boot sector; on a hard disk, the equivalent area is called the Master Boot Record.) Once loaded, the virus can then infect any other disk used by the computer; a disk-based boot sector virus can also infect a PC’s hard disk. Most boot sector viruses were spread by floppy disk, especially in the days before hard disks were common. Since removable disks are less widely used today, boot sector viruses have become much less prevalent than they were in the early 1990s.
