Is deleting the Qur'an from a computer prohibited?

I know it is forbidden to burn or desecrate the Qur'an in anyway and we must treat it with utmost respect. Is deleting the Qu'ran from a computer the same as burning the Qur'an? What is the difference? If my college friend sees the Qur'an on my computer and deletes it in malice, then is he committing a sin?
