That is the Master Boot Record and that does contain executable code at the end of a disk parameter table. The point is, the code has to be executed in order to cause an infection.For the most part, media files cannot get infected, and if there is virus code in them, the player or viewer will consider the files corrupted and either try to play/display the corruption anyway or abort with an error. There are a few exceptions such as the few media files that allow executable code or scripts to be attached.
