Previously i've posted a
tutorial about how to
create a fake facebook virus. This virus prank is similar to that one, but instead of
notepad i will use a "New Shortcut" option and
command prompt to create it. This “virus” can shutdown, restart and
log off your pc (Can also write a message and specify the countdown time). This is actually a faster way
to turn off
your pc, ’cause it doesn’t require clicking Start>Turn off....
And absolutely the best thing about this virus is that you can make a fun prank to your friend... :P
Now lets start with the tutorial.
1) Create a shortcut (
Right click on your desktop and go to new -> shortcut )
2) After this will appear window and that is where you type the code
shutdown -s -t 300 -c "Your Message"
To log of computer type
shutdown -l -t 300 -c “your message”
To restart
computer type
shutdown -r -t 300 -c ” your message”
The
number after -t is the number of seconds countdown there will be before
shutdown . After -c write own message , that will come up when
shutdown box pops up.
3) Click Next, Finish
4) After this will appear icon on desktop, when someone click it,
shutdown box will pops up.
Also you can change the look of your icon (Right click on the icon -> Properties -> Shortcut -> Change Icon and replace it with your own one, like Internet Explorer or
Mozilla Firefox...)
5 ) You can stop system
shutdown by going to Start->Run , then open cmd, write
shutdown -a and
press ENTER on keyboard, as shown below

That's all. I think this is one of the simplest way to create a fake virus, but still to make a fun of your friend.
