Basically it is just the Vienna virus - the variant in the book by Ralf
Burger to be specific, with an extra twist. When an infected program is
run, the virus will search for other programs to infect, but also try to
place a modified copy of the Ping-Pong virus on the diskette in drive A,
provided it is a 360K diskette. This Ping-Pong variant has been changed,
so that it is not infectious, but it will also work on a '286 machine.
