Description:: Nasty is a bit of fun. It is ideal for worrying PC owning friends or colleagues.
Simply install it on a running PC, and the very next time that the computer is rebooted, Nasty will pretend to format the C: drive! It is VERY convincing.
At the next reboot all is back to normal!
(Emergency recovery file is created, but to my knowledge has never been needed!)
