Create a Fake and Harmless Virus

This virus prank is effective to scare your friend, 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 beforeshutdown . After -c write own message , that will come up when shutdownbox pops up.

3) Click Next, Finish



4) After this will appear icon on desktop, when someone click it, shutdownbox 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.
