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.

Virus Prank 2: http://www.instructables.com/id/Virus-Prank-2/

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 =]

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

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++.

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!
good idea tis is what i want to do to my sister i want to make one of viruses and make it say "WARNING:A VIRUS HAS BEEN DETECTED TO SAVE YOUR COMPUTER GIVE ALL RESPECT TO YOUR BROTHER AND LET HIM FIX IT!" and after she gave it to me i would quit the currant virus and make one the reproduces like 1,000,000,00 times
fork bombs FTW
or put a shutdown command in startup... MUAHAHA
hey man i did this its so awesome! i made different messeges too! like one is "hi!" then you exit and its "whyd you do that?" and so on and so forth its so funny! thx thinker!
cool, what do u type in notepad for it?
thinker that is quite cool
On the Macs at our school, we opened Stickies, typed in a virus warning type message, turned up the volume, and told the computer to use the speech service. As we left, the computer started spouting off stuff about corrupted disks!
Then we reprogrammed the shortcut keys so that they would all make the current program quit or do other annoying stuff.
lol, nice idea.
Certainly are a thinker! : D
i dont get it. i add the code, save it, then what
then click file, save as background, CENTERED, and wait! : D

what is print screen? how do you do step 2?
Print Screen is called: Print

Print Screen in a botten
that takes the WHOLE screen as an image.
In paint, and you've pressed Print

press Ctrl + V or right click and press Paste.
I hope that helps.
a button...

WHAT IS PRINT SCREEN?? sorry for caps letter my bad.
If you don't know what "Print Screen" is, it is the key that says: Print
it is RIGHT on top of the "Insert" key.
Happy now? Good!
mkane marci244 years ago
Print screen is a button on your keyboard that takes a picture of the whatever is displaying on your screen. The buttons usually near the top right of your keyboard!
After you press that you can paste the picture of your screen into windows paint or something else that can display a jpeg file!

OMG! I set it on my mom's user and now i'm waiting for her to see it! another thing you could do is copy and paste tons of the virus messeges so they cover the whole screen! or browse "ERROR" and create an error instead of a virus. THIS IS AWESOME!
wow. I almost got grounded. How was i supposed to know she had to get on her computer at 4am to get tickets to Spain?!
lmfao! I know!
i applied this trick to the main CPU at the police station. 250 hours of community service. w00t!
I don't believe it! Do you work as a police officer? Or did you break in and do it?
Broke in, lol
Wow... that was smart
I know....narrowly escaped jail time
thats scarily close
i dont think you should do that again rofl :)
lol, 250 hours.....jail time.....??? No thanks, im not trying that
No, not jail time, community service. They thought of me doing jail time, though.

Why don't you just make it run something that pops up in the event runner. So if they try to go on the internet it comes up saying something about a virus. Much more practical plus they would think it was their fault. say if it wasn't their computer.
  a nerd in my class freaked when he saw the message and couldnt close the "window" he then restarted his computer to find the same message the teacher was wicked mad and then yelled at him for ruining a computer

A good one we do at our school is to go up to someones computr while theyre out and hold down Windows + E. It brings up lots of copies of My Computer and they can spend hours clearing them off.
Or they could just right click the task bar and "close group" or restart explorer.exe
Yeah we do that too. Or hide the desktop icons.

If you want to jam a Windows computer, go to C:\Windows\system32 and then press Ctrl+A, Enter. This will open every single file in this folder. As there are a lot files, the computer will immediately become useless. =) Very simple but very effective.

print screen is what it means, if u are using a laptop it prtsc should be next to F12. If you are using a desktop computer with a big keyboard then it should be on the little square of keys and also next to the F12 button. :) I hope this helps
dude this is cooler i think so i did it in my school and the principle was like on the announcements that shes gonna question everyone in the computer lass awesome and my friend kusha...whos iranian... ahahaha he got in trouble because they suspectd him for no reason lol i feel sorry for him but he laffed his arse off u know?x=msgbox("WARNONG! YOU HAVE VIOLATED COMPUTER LAW B23 AND C34 YOU HAVE BEEN DELETED FROM ALL SYSTEM USERS...YES, THIS WOULD BEA PERFECT TIME TO PANIC!",vbCritical,"VIRUS")
then save as (HOT TEACHERS NAME HERE) Naked in bath.vbs that will usually work for it but if u think u wanna name itr something that everyone will open go ahead... and if u really wanna mess around copy and paste the code like 100 times and make it pop up alot...yay
then change the icon to like the teacher or w/e a pic of watever you put the title as... or even put it as EnternetExplorer.vbs then put icon as the orbiting e woot fun fun fun

If you hover the mouse over the top of the start bar, it will turn into one of those verticle double arrow thingies. You can drag the start bar down to the bottom of the screen, and it won't pop back up until you drag it back up.
no the one from the screen shot gets hidden under the real start bar.

how do i get into ms paint
Also found in C:\WINDOWS\System32\ I think... Look under MS Paint
Shadow Dragon (author)  genius kid7 years ago
Search it. Go to the start menu, and on the right side, you should see a magnifying glass that says, "Search" next to it. Click on that and click on "All files and folders" and then type "MS Paint" into the box that says "All or part of the file name:" and make sure the drop down menu says, "Local Hard Drives (C:)" Then do search. And when an icon comes up that looks like paintbrushes and artistic tools in a cup, double click that.
You dont have to just go to start>all programs>accessories>paint
if you have administrator rights: Start>Run>"mspaint">ok. exclude the quotation marks
