Fake Shutdown Virus

Now that's a trick that can make your friend go on their nerves. This mimics a virus sort of thing ,if your friend is not aware of such things.. most people don't.!!

It displays a message that can be customized by you . After completion of its course it shutdowns the computer making the user confused as what happened

now let me show you how it works and then we'll customize it to look real so that a friend gets pranked

Step 1:- Go to your desktop , right click new shortcut

Step 2:- Now when you click on the new shortcut a window will open up
             In that type shutdown -s -t 30 -c " Stop me if you can "
             After that click next and save the name as shutdown.exe and you are done with it

Step 3:- Now talking bout customization you can change the time in seconds to anything that you wish and the message also to anything you wish . Change the icon to some game icon and change the name to setup.exe

And if you have access to the friends computer then copy this thing into the start up programs and you're done

Every time the user turns on the PC the program will automatically run at start up and the system will shutdown

How to stop this ..?
go to run
type shutdown -a
and the program will terminate

Any suggestions ? , most welcomed .!!

 note :- works perfectly with XP but in windows 7 it does not display the message
