for making the trolling viruses, you need to be able of changing the file formats (like - from .TXT to .VBS, etc.) so if you have Windows 7 the first thing you do is -
1. go to "start menu" then "control panel" and then "folder options"
once you hit the "folder options" a window will pop up. so -
2. switch to the "View" and remove the thick from "remove extensions from known file types" and then hit "Ok".
so we're able to change the file formats.
3. create a notepad file
4. copy and paste the script in notepad
----------------------------------------------------------


msgbox "dont"
msgbox "u"
msgbox "hate"
msgbox "the moments"
msgbox "like this?"
do
msgbox "come on, turn me off :P"
loop

----------------------------------------------------------
5. save the text and quit the notepad. then rename it and write .VBS instead of .TXT
_________________________________

that's all. this script above pops up a messagebox window, (with a text of your wish in case you edit it) and it's impossible to close for the victim.
though there's a way to shut it down without restarting your PC - start task manager, switch to the processes and shut down wscript.exe

if you just want to amaze the one you're sending this to, but not troll him/her than do so -
...
...
...
...
msgbox "like this?"
do
loop
msgbox "come on, turn me off :P"

in this case the messagebox will close after u hit OK for the 6th time, after "come on, turn me off :P" this shows up.

that's all, we got lots of other scripts but we cant just give them away, as they're more valuable. though you can add the main admin (me) in friends and get other scripts for inviting +100 friends to the group for example, etc.
enjoy men !
