A boot sector is a particular area on a computer's hard drive, floppy, or other data storage device. It contains information
on the disc's file system and a boot loader program that is responsible for starting the operating system.
There exist a number of viruses that infect boot sectors, which are thus called boot viruses. The Kaspersky Lab
application allows scanning boot sectors for viruses and disinfecting them if an infection is found.
