A boot sector virus is a virus that infects the boot sector of a computer's hard drive. The boot sector is the area of the hard drive that contains the bootstrap program, which is responsible for loading the operating system when the computer is turned on. A boot sector virus replaces the bootstrap program with a malicious version that is capable of infecting other bootable media, such as floppy disks and USB drives.
Boot sector viruses are typically spread by infecting floppy disks or USB drives that are used to boot the computer. When the computer attempts to read the boot sector from the infected media, the virus is executed and can infect the computer's hard drive. Boot sector viruses can also be spread by email attachments or via malicious websites.
Once a boot sector virus infects a computer, it can be difficult to remove. The virus may prevent the computer from booting properly, making it difficult to access the files needed to remove the infection. In some cases, the only way to remove a boot sector virus is to reformat the hard drive and reinstall the operating system.
