This virus will only infect hard drives when an attempt to boot from an infected diskette is made. Once the virus has infected the hard drive, all non-protected floppies used in the machine will be infected.
Unlike most other boot sector viruses (except Form), Boot-437 infects the DOS boot sector on hard drives instead of the Master Boot Record.
