I'm still confused - HOW exactly is an un-infected computer supposed to get infected through a sound wave? The mic jack means nothing to a computer and is NOT a data communication port, so the only way for it to translate sound into data is through a program that can interpret it. But, if it takes software to interpret the sound into actual executable code, what's the point of interpreting sound in the first place? Why not just include the entire virus as a single package? The only answer I can think of is "it helps elude anti-malware programs" but I find that a little hard to believe. Either way, the virus idea is really creative.
