[comp.virus] Virus Demos?

ash@uunet.uu.net (12/01/89)

 I have seen conflicting descriptions of what the Marijuana virus
displays on the screen.  Not being afflicted myself, touch wood, I
don't know whom to believe.  Three sources I have seen claim that the
"Legalise marijuana" message is seen, and ALan Solomon recently said
at a Melbourne seminar that this message is embedded in the virus
code, and is not seen on the screen.  This anomaly is a minor issue,
but it set me wondering how does the average user (beginner) know when
a virus has struck her/him?  There is no shortage of virusbusters able
and willing to help such people for a fee.

It would be a good idea for someone who has samples of all known
viruses to create a "virus demo" program using something like Dan
Bricklin's Demo for the purpose.  I haven't seen this program (DB's
D), so I don't know if it could mimic all viruses.  It would also not
work with a virus that does its damage in the background and leaves no
screen message.

Our user group would like to create a library of viruses for testing
new antivirus programs, but I appreciate that no self-respecting
custodian of samples would turn over copies to us without some
cast-iron guarantees of keeping the samples under lock and key.  Hence
the suggestion for a harmless virus demo for known culprits that leave
a screen symptom.
