[comp.virus] Assorted Viruses, anti-viruses, programming

DRAGON@RCN.BITNET (11/29/90)

I am interested in learning what the different types of viruses there
are.  Some of their symptoms, techniques of infiltration, etc.  I've
read this list for a while (and even posted something about the Whale
Virus), and want to learn as much about these viruses as possible.
Forwarned is forarmed...

Also, I know that many people who are virus-makers do so for malicious
delite, for the most part.  Just to be immortalized, I guess, or maybe
they are sadistic?  Anyways, I was wondering if anyone knows of anti-
viruses created by other semi-malicious people who create them just to
irrate the virus-makers.  I don't mean manufacturers who create the
disinfect programs, I mean someone who makes a program that is spread
like a virus, reproduces itself, and only destroys viruses.

Someone mentioned how the Stealth viruses will remove their presence from
a piece of programming being used/scanned.  If this is so, how are they
dangerous?  If everytime it is used, it just goes elsewhere, what harm
does it do, except for accidental erasure of segments of a program?
Although I guess that the extra memory would tend to waste disk space...

What kind of field is out there for anti-virus programmers?  Who would
hire them, and how much computer knowledge would be needed?
Come to think of it, what languages are most used to create viruses and
the disinfectant programs?  Just wondering.
