Boot-437

Threat description

Details

CATEGORYMalware
TYPEVirus

Summary

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:.

Boot-437 doesn't do anything except replicate.
