Has anyone here ever written a virus? Does anyone know someone who has? Is this an offshoot of [random] hacking or are these programs written with a specific intent? In other words and as an example, are viruses typically more about causing damage to the economy, or a particular company, say as by terrorist or other political or corporate "enemies", or are viruses the product of teenage boy[?] hormones and people with nothing better to do? Is there a natural progression to the evolution of viruses or are viruses typically one-off with no natural relatives.
