That's a boot sector virus and must be removed the old fashioned way - with a bootdisk and a DOS scanner. That virus has been around for 12 years.

Try EMSCAN.ZIP. Unzip it onto a floppy, and make a basic bootfloppy (do this on a different known clean machine) and write protect both floppies. Boot with the bootfloppy (after making sure the floppy drive is first in your boot order) then insert the other floppy - and run BOOTSCAN.
