Create a very real looking virus in under 5min
Step 1: Download This File
You Probably should download the main file to some folder that wont be too easy to find (I will refer to this folder as the "hidden folder") and make a shortcut of the main file on the desktop then hide the main file (go to properties and click on the "hidden" box)in the hidden folder and also,hide all firefox/Internet explorer shortcuts from desktop or you can just move it to the hidden folder
(i modified this script with AutoHotkey and copied some parts from http://www.autohotkey.com/forum/topic27784.html&highlight=prank
then i compiled the file so u don't have to do nothing with it)
Step 2: Rename the Shortcut and Change the Icon
Now Change the shortcuts name to Internet explorer/Mozilla Firefox (which ever the target uses)
then go to their IE/MF properties and goto "shortcut" tab and click on "Change icon" and copy the address(ctrl+c) and then close both properties windows and open the main files's properties and open the "change icon" and then paste(ctrl+v) the Firefox/explorer's icon address in that box and click "ok" then choose the icon u want and click ok...
Step 3: Ur Done!!
Now wait till the target uses the shortcut u made and in about 4 second a black screen will popup and say its deleting ur files..it will not harm the pc it only reads the files from ur harddisk and put "Deleting" in front of those files it reads..
~in case the person goes tottalo nuto and jumps through a window and starts shooting people with his/her laser eyes u can stop this prank by pressing "s"
~when the progress bar fills 3/4 way(or something like that,i forgot)it will pop up another message box and then shut down the pc so be prepared..
