You seem to misunderstand the importance of this file, and what could happen if you change the internal assembly to a write code. If you add write features to this sample virus code, it will not be pretty to your OS. The fact that you can do an Assembly code analysis, as I did above, proves that the researchers whom designed it, were specifically aiming for what real virus code would look like. If you do an analysis (if you know Assembly code) of this file, you will realize it has all that is needed to implement a real virus. It contains an instruction pointer, a stack pointer, a data string,
