In 1986, the German programmer Ralf Burger discovered the possibility of creating copies of his program by adding his code to executable DOS-files of the COM format. A prototype of the program, called Virdem, was demonstrated during the Chaos Computer Club secret meeting  (December, 1986, Hamburg, Germany). This was the impetus for writing hundreds of thousands of computer viruses that partially or fully used the ideas described by the author. In fact, this virus laid the foundation for mass infections.
