Picture of Virus Prank
This will freak out your friends or whoever you do it to! They will think that their hard drive will get fried. It is completely reversable.

Step 1: Run the VIRUS

Picture of Run the VIRUS
In the start menu, there should be something that says "Run". Click on that and type in "VIRUS" and press OK. An error message should come up with the title "VIRUS".

I love your wallpaper illusion, do u know where i can find it?

How about using whatever pic they're already using as wallpaper?

just search optical ilustions cuz thats what it is. watch it really close in the middle and the spin

Anyone who is even remotely intelligent could know that this is bogus... First off, Windows wouldn't type in all caps. Second, it wouldn't say "SHUT YOUR COMPUTER OFF RIGHT NOW AND TAKE IT TO A PROFESSIONAL TO PREVENT YOUR COMPUTER FROM NEVER WORKING AGAIN!". Third, if Windows did happen to display a message signaling the user of a virus, they would be able to hit okay.
If you were truly stupid you would unplug it and take it to Geek Squad unlike us at Instructables. We do all of our own computer reapairs!!! If you want to do a REAL prank open Notepad and type in :

@echo off
echo Warning (Random Virus Program(AVG Anti-Virus) has detetected a threat.
echo Booting in Command Prompt to avoid detection
pause> nul
echo Virus Type:
echo Trojan Gen. 3
pause> nul
echo Attemping to remove virus...
echo Loading file location C:/Mycomputer/system32/WINDOWS/GENWS1
echo FHHJG^$HNY^U&^%J&I5ujk67MKUY&^IMJK67jii86iuht5e4y47uh65u7
echo Virus removal failed...
pause> nul
echo Virus too advanced. Loading file locations:
echo Anti-Virus detector.exe is corrupted...
echo System Shutdown in progress...
echo Shutdown is in progress to protect data...
shutdown -m

Save it as Internet.bat and save it on the victims desktop. WAY better than this!

hey shadowdragon
a much more effective thing to do is something i used to do in my school
if you open notepad
type in
and copy and past that about a bazillion times
then save as virus.vbs
or whatever you want to call it
then change the icon and copy and paste it over the items in the desktop
then everytime they try run something on the desktop (usually when they try open internet explorer or firefox) it runs that and displays the message
it doesnt harm anything on the computer at all
takes about 3 seconds to put all the icons back to normal
but it is an actual messagebox that pops up
and cos it says "vbcritical" it actually makes the sound a critical error makes when it opens
and cos youve copy and pasted it
whenever they close it
another one opens =]
for a good while anyways
or you cud have it as one of the programs that runs on "startup" of the computer
but that means it will bug you as well
and in school or office you might get told off for "editing the logon script"
whereas with my way they just sorta sigh and giggle a bit once they realise
but it still scares the bajeesus out of peoples


Have Fun With This!!!!

also known as Mong or El-Mongo
what do you mean "then change the icon and copy and paste it over the items in the desktop" ?
You can use a Do/While or a For/Next loop.
you can
but that wud create an infinite loop, unless i created a perimeter such as index+1 stop when index = 30
or something
which is needlessly complicated when doing something just for fun
and requires declaration of variables and shiz, which when doing something for fun like this, was totally pointless

So yes, i could have used a do/while or for/next loop, but i found that when im making something that is going to be deleted when found, copy and pasting a line 30 times seems a lot better(quicker), then actually fully scripting something.

but it is considered bad practise to do so i suppose =]

best code ever.

dim one as integer
one = 1
if one = 2 then quit
else msgbox "one does not yet equal two"

also try: do system.diagnostics.process.start("explorer","") beep loop
thinker me!7 years ago
yeah i knew that one =p
best thing i found
was a backdoor into our college computers
(they use Novell)
that let me edit the logon scripts of one computer
all i did was edit it
and then get it to save to the persons account
cos they all had a virtual drive
and then it copied to the next computer
which when someone else logged onto it copied onto Their login script
it was really really simple coding
and it ran a .vbs program
that beeped
3 times
while they logged in
and while almost unnoticable at first
3 beeps on one computer
when 3 people have it
then 9
then 27
as more people use the computers used by the people with the script
suddenly the first minute of any computing lesson was filled with loud beeps

i love that beep command
That sounds like that the computer is gonna explode; freaky
Dude, post the script for that! plz
another good one for noobs press CTRL + ALT + UP key press CTRL + ALT + DOWN to reverse only works on intel graphics

works on nvidia also
haha that's beautiful

thats also silly - change your privileges to administrator using regedit (this is not always necessary) then change the shortcuts so they link to the program. Also, instead of just going a virus has been detected it is much better to make a timer event, output the time in a box and make the computer shut down when the timer reaches zero or if you dont want to shut it down make it open a box saying virus cleaned
CyberJacob me!4 years ago
you need admin privileged to use regedit
How can I link this script to shoudown.exe so that when the victim clicks the "OKAY" button, the shutdown command runs with a timer, so they think something sacary is really gonna happen?
Sorry for bringing back posts an old 'ible, but you can link the .vbs script to "shutdown.exe" by adding these lines:

Dim timeinseconds
timeinseconds = (put a number in between these parantheses)
Set Wshshell = CreateObject("Wscript.shell")
Wshshell.run("C:\WINDOWS\SYSTEM32\shutdown.exe " & timeinseconds)
You could do that with C++.

or... you can write


and it will go on forever in a very nice 1k package

how do u stop this with out logging off or shutting the computer down
Ausm wangtrevor5 years ago
Press Ctrl+Alt+Del or Delete to open up the task manager. Then click on the Applications tab, look for something that says vbsscript.exe or something along those lines, it should have a rather colorful cube as an icon. Then click on that and click on end task on the bottom, it'll take a couple seconds but it will go away. And if you can find the same thing on the Processes tab and click end task, it should end immediatly.
For Vista and XP it is: wsscript.exe
lol, I did this a couple of years ago to my computer teacher...
not the exact same thing, but popups filled the whole screen....
The result = a year of being banned from school computers, and a couple hours of community service...

not my best decision, but funny all the same
the computer administrator actually called in a professional computer expert to delete the little batch file...Those admins are soooooo smart at my school!

(funny how one line of code can get you screwed over! :) )
put it in startup it really screws with the computer
I did that once, only I didn't get caught. The way I did it is that I put it on a website.
lol, our admins dont care. untill my friend managed to get a cpu beep loop on every single computer on the school. that was rat.
hahaha!!! brilliant!
