  I don't know what you mean by "Scanres checked out ok at 640K", but
if you'd read the instructions which came with Immune, you'd find that
it says:

  "Note: On some machines (e.g. PS/2, HP Vectra), IMMUNE (and CHKDSK)
will report less memory than is nominally available.  For example, on a
PS/2 with 640K, IMMUNE will report only 639K even when no virus is
present.  This is due to an extended BIOS area.  In order to be certain
that the deficiency is not due to a virus, perform IMMUNE immediately
after booting from your original (write-protected) DOS diskette.  If
you find only 639K you know that the missing 1K is not due to a virus,
and that 639 is the parameter which should be supplied to IMMUNE."

  So the chances are good that you don't have some mean and nasty bug,
and the moral is: "If all else fails, try reading the instructions."
