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.
To disinfect, cold boot from a clean bootable floppy that has the same
version of DOS as on your hard drive and SYS.COM. Then issue command
SYS C:.
