STEP 1
Go to desktop , right click go to new and click create new shortcut.

STEP 2
You will be asked to type a location in at this point you type in shutdown -s -t 60 -c "your computer is infected"

[/b]STEP 3
Then after hitting ok you will be asked what you would like to call your shortcut, i called mine pics, so later on when i was complete i could trick a friend.(it is also adviseable to change the icon of the shortcut to make the whole thing more convincing, you do this by right clicking your shortcut then change icon)

STEP 4
After you have completed all of these steps it is adviseable to test the so called virus by simply opening the shortcut up as you would with any normal program, then on your screen should appear a window saying your infected and a timer should also be ticking down, at this time you cannot do anything else so you leave the timer go down and then your pc will turn off , once your pc is off simply re-start the pc and no damage would have been served to your pc at all.

STEP 5[b]
Be sure to type the location in the same way i have leaving spaces as i have done.YU SHOULD NOW BE LEFT WITH A PROGRAM THAT CAN SHUT A FRIEMDS PC DOWN , SOO THERE YOU GO A FUNNY PRANK TO PLAY
