Not sure if this is the place to ask but I couldn't think of anywhere better. Is it possible for the codec or DRM of a video file to become a virus if it is shared? and would it be legal in the US or UK? The reason I ask is I just got a message from someone saying they are thinking of using such a thing in their videos. The message said "Imagine an encoding matrix codec that forces you to lower your anti-virus protection to receive a file and then, if the file doesnt come with a system generated Key...BOOM...hiroshima......" I tried googling but couldn't find any mention of it.
