The Devil virus is a reasonably simple diskette and Master Boot
Record infector. It is only able to infect a hard disk when you
try to boot the machine from an infected diskette. At this time
Devil infects the Main Boot Record, and after that it will go
resident to high DOS memory during every boot-up from the hard
disk. Disinfection & Removal Devil can be disinfected from hard
drives by booting clean and giving command "FDISK /MBR".
Floppies can be disinfected with the FIXBOOT program provided
with F-Secure anti-virus products. Once Devil gets resident to
memory, it will infect practicly all non-writeprotected
diskettes used in the machine. Devil-virus is also a stealth
virus - if you try to examine an infected boot record, it will
show you the original clean one instead. This virus has one
nasty side effect; all floppy diskettes that are infected cannot
be read by DOS unless the virus is active in memory. This is due
to the fact that the virus overwrites part of the floppy disks
