And when you get caught, shout "IT WAS A VIRUS!!!! CLONING IMAGES!!"
I dont think I have ever encountered a virus that cloned images. The only way I can even imagine it true is if a malfunctioning root kit was somehow installed and affected file writes....but in 30 years..haven't seen it. Likely they were just lazy so they kept handing out the same image figuring no one would know.
