time previously when I've had so many viruses hitting us and getting thro our
scanners with nothing we can do about it. I dont recall seeing viruses with
variants as high as 'j' before, especially in the relatively short time since
the previous variants were outSeriously, drop some references if I'm off-track.. its just my perception and
I'm not an expert at all with viruses...
They are getting batter at it, but the WANK worm (1989) used
self-modifying code so that no two replicas were the same. (Note: This
worm only infected VMS systems running on the global DECNET internet,
mostly DOE, NASA, and DEC corporate systems.)
