Lock is a small program that will stop your system dead.
Once started on a unknowing victim, they’ll have a dead computer to deal with! Only the meanest person would send this to a friend and trick them into installing it. Mean, evil, vile are only some of the words that could describe you. Enjoy!
This is a great little prank!
To EXIT just move the mouse into the top left of the screen 3 times or give it the 3-finder salute:
Press at the same time "CTRL" and "ALT" and "DELETE" and in the CLOSE PROGRAM WINDOW highlight LOCK and click on END TASK.
You may need VBRUN300.DLL to make this prank work. If you do get such an error, search how to do it .
