What is a boot sector infector?
A boot sector infector is a virus that exists in the bootstrap record of thumb drive, floppy disk or hard disk. It loads into memory when the computer is “booted” from an infected disk drive. Boot sector infectors spread when you access a writable thumb drive or floppy disk from an infected computer. The infected copy then becomes a carrier for the virus. The virus is spread to other hard drives when an infected disk is used to start up the computer. This happens most often when a thumb drive or floppy disk disk is left in a computer and then the computer is turned on or rebooted.
