"Computer Viruses: A High-Tech Disease," by Ralf Burger, published by 
Abacus (Grand Rapids, MI). c. 1989, 276pp, $18.95 suggested retail.

        This new book about computer viruses is so detailed it 
includes viral programs you can type in yourself just so you can see 
how a virus works!  The programs, listed in assembly, BASIC, and 
Pascal are probably the most controversial section of the book, but 
the author argues that it is people without knowledge who pose a more 
serious threat to the future of PC security.  The more people know 
about something, the less "mystery" it aquires.
        "Computer Viruses" is written on many levels and most parts 
can basically be understood by anybody with even a limited knowledge 
of programming and computer literacy.
        Surprisingly, the book does make mention of the Atari ST and 
Amiga, therefore realizing that there are other computers in the 
universe besides the IBM.  (Did you know in Germany there is a 
program released called the Virus Construction Set for the Atari ST?  
You can custom-make your own virus to play havoc with your and 
other's disks!)
        The last few pages make reference to the future and the 
author talks about the future of viruses when coupled with Artificial 
Intelligence.
        All in all, the book is fascinating and comprehensive.  Get 
it.
