Why? I don't think the police are going to let someone off just because
there's no metadata.

More simply, the author of the malware could just release a
pornography-viewer application which read data bizarrely stegoed into
the interstices of your hard drive, by a worm which never itself touches
the disk. Neither the worm nor the viewer leave any metadata, by design.
