Creating a computercraft virus, any ideas?

Ok, so I'm pretty adept at lua, and I'll take and attempt any suggestion as long as it's not too crazy or something that I just can't do. Currently the virus is called "iloveyou", it locks your computer, changes the id, deletes all the files, and auto ejects an inserted floppy disk. the best part is the heart animation that floats across the screen.

Malicious code is not allowed here.
