Step 5: Fake virus detected(HARMLESS)

Picture of Fake virus detected(HARMLESS)
Ok this will make the victim think they have got a virus when they click on an icon such as my computer.
First we have to open notepad again
1.type this in or copy.
@echo off
echo WARNING VIRUS DETECTED
echo System check
echo -
echo Hard drive - FAILED
echo -
echo RAM - FAILED
echo -
echo Disk Drive - FAILED
echo -
echo Connection - FAILED
echo -
echo code 754*sd56625
echo -
echo Hard drive must be formatted to resume windows
echo -
PAUSE
echo -
echo -WARNING
echo -
echo Hard drive has been formatted
echo -
echo -WARNING
echo -
PAUSE
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
echo APRIL FOOLS
pause

2.Save as a.bat
3.convert the a.bat to an exe file which lets you name it and change the icon.
4.to convert it you will need to goto www.f2ko.de and download bat_to_exe
5. put it on some ones computer and watch them freak out

RESULTS
Look at the screen shot below and this is what the person will see. where it says pause you have to press a key to see the writing below it.

P.S WHEN YOU ARE CONVERTING THE BAT FILE TO EXE USE ONLY THE TOP 4 BOXES IN THE CONVERTER

Did you change the .txt to "all files" @ the bottom? If not, do that, then it'll work

I only have the option of saving the code in Notepad as a txt file!

Just name it ending with ".bat" (w/out the quotes) and it'll be OK :)

Change the .txt to "all files" @ the bottom

To Jimmy 1:
you must change the .Txt file @ the bottom to "All Files". then it will be able to change to a .bat file

I prefer the ever so funny

start iexplore.exe http://www.youtube.com/watch?v=UJ8Eya7EWqI

at the very end rather than april fools
something else you can do is add instead of April fools echo -WARNING echo - echo Hard drive has been formatted echo - echo -WARNING echo - PAUSE echo System needs to restart in order to continue processing PAUSE echo Windows is shutting down PAUSE shutdown -t 30 the shutdown -t 30 is telling the computer to shutdown in 30 secs, you can change it to whatever you like or shutdown -r to restart your computer
If you hide all of their files, both in My Docs and My Computer, before setting this up, then use the code to shutdown/restart the computer, it'd make them actually think their files are missing. Though, you'd need a way to get the non-Windows-standard icons to disappear upon starting up again. Not sure how that'd be accomplished...
Right-click on the desktop in question. Go to "Arrange Icons By" (usually first option in the dropdown menu), select "Show Desktop Icons". This will have a check-mark by it if there are icons already on the desktop. Selecting it again will remove the checkmark, and remove/hide the desktop icons. Following these steps again and re-checking the option will bring the icons back.
how does it works....????

that is mean spirited
Oh well. It's all in fun and completely harmless.
TWSS! @kvswim

You should put the shortcut to shutdown in startup folder! would be hilarious!

Ahhhh.... good harmless cmd line fun.
i bet every one wishes they were as coll as us
Has anybody used this? I just want to make sure it won't mess up the computer. Does it hurt if you change some of the text? (not the echo part, the part after that.)
its all good echo means that it will desplay a message and pause means that the program will wait until you press any key to continue the program; and no all that will happen will be that the text on the cmd window will be different

ok he is useing a harder to do way an easer waay is like this

@echo off
title VIRUS
color 04
cls
echo Do you wish to erase c: / drive (y/n)
ping localhost >nul
cls
echo Are you shure you wish to erase c:/ Drive? (y/n)
pause >nul
cls
echo Searching for c:/ drive...
ping localhost >nul
dir /s
dir /s
echo.
echo.
echo.
echo.
echo Erasing Files...
ping localhost >nul
cls
echo Files erased!
pause
msg * You have just been pranked!
exit

thats it another one this one shuts down your computer instantly save it as a .bat file

shutdown -c "Virus Activated" -s -t 1
thats a good one

ya but my system say 16 bit MS-dos subsystem the ntvdm cpu has encountered an illegal instruction chose 'close' to terminate
Question then. What is best way to remove this afterward
You don't really need to remove this. It's completely harmless and if you want to get rid of it just delete it like you would a normal shortcut or program.
Or just type!: Del %0 _______________________________________________________________ at the end!
Delete it. Of course!
dean-101 (author)  last1whoknew6 years ago
use the del command at the end of the code, look below: @echo off echo hello pause del C:\testfile.txt <<

Tell me how that one works out XD

what does 'echo' do?
This needs no explanation. Goto Command Prompt and type echo without the brackets and press enter. The computer will then display (on the next line) what you typed in. Simple.
max44205 years ago
an you can add a title only by typing title after @echo off
max44205 years ago
you can add mode 200 or mode 900 after the @echo off to make it bigger

Also, if you don't want to download the bat to exe converter you can just make a shortcut to the file, then you can change the name and icon.
