Step 1: Where to Create Your Devious 'Virus'

Goto notepad. All Windows computers come with this simple yet usefull program. Hold down the 'windows run key + r' and then type notepad or go through your start menu. (start - all programs - accesories - notepad)

Step 2: The Batch File

Now type the following into notepad EXACTLY HOW YOU SEE IT! (What's better is just to copy and paste. . .)

@echo off
echo WINDOWS HAS DETECTED A VIRUS, WOULD YOU LIKE TO TERMINATE?
echo -
echo PROCEED WITH VIRUS TERMINATION(Y/N)
set/p "cho=>"
if %cho%==Y goto forward
if %cho%==y goto forward
if %cho%==n goto Shutdown1
if %cho%==N goto Shutdown1
:forward
echo VIRUS HAS BEEN DELETED
Pause
echo PLEASE ALLOW WINDOWS TO PREFORM A SAFETY CHECK
Pause
echo SYSTEM CHECK
echo HARD DRIVE - FAILED
echo -
echo RAM - FAILED
echo -
echo DISK DRIVE - FAILED
echo -
echo CONNECTION - FAILED
echo -
echo WINDOWS SUGGESTS YOU DELETE ALL FILES TO RESUME(Y/N)
set/p "cho=>"
if %cho%==Y goto Sucess
if %cho%==y goto Sucess
if %cho%==n goto Shutdown2
if %cho%==N goto Shutdown2
:Sucess
echo WINDOWS HAS DELETED ALL FILES
echo -
echo PLEASE ALLOW WINDOWS TO PREFORM A SAFETY CHECK
Pause
echo SYSTEM CHECK
echo HARD DRIVE - FAILED
echo -
echo RAM - FAILED
echo -
echo DISK DRIVE - FAILED
echo -
echo CONNECTION - FAILED
echo -
echo WINDOWS IS SHUTTING DOWN IN 20 SECONDS TO PROTECT FROM DAMAGE
goto Shutdown3
:Shutdown3
shutdown -r -t 20 -c "APRIL FOOLS! HAHAHAHAHAHA"
:Shutdown1
shutdown -s -f -t 60 -c "Windows is shutting down to prevent any further damage"
:Shutdown2
shutdown -s -f -t 60 -c "Windows is shutting down to prevent any further damage"

Step 3: Explanation

Ok for those of you who are skeptics or unsure about this, I'll explain what it does:

@echo off ------> Hides the code, looks more professional
echo WINDOWS HAS DETECTED A VIRUS, WOULD YOU LIKE TO TERMINATE? -----> writes this on screen
echo -
echo PROCEED WITH VIRUS TERMINATION(Y/N) \
set/p "cho=>" \
if %cho%==Y goto forward }--------> Gives the victim the choice whether or not to proceed with the choice "Yes" or "No"
if %cho%==y goto forward /
if %cho%==n goto Shutdown1 /
if %cho%==N goto Shutdown1 /
:forward
echo VIRUS HAS BEEN DELETED --------> same thing for the rest, writes this onscreen
Pause ---------> tells victim to press any key to continue
echo PLEASE ALLOW WINDOWS TO PREFORM A SAFETY CHECK
Pause
echo SYSTEM CHECK
echo HARD DRIVE - FAILED
echo -
echo RAM - FAILED
echo -
echo DISK DRIVE - FAILED
echo -
echo CONNECTION - FAILED
echo -
echo WINDOWS SUGGESTS YOU DELETE ALL FILES TO RESUME(Y/N) -------> same thing as above, gives a choice again
set/p "cho=>"
if %cho%==Y goto Sucess
if %cho%==y goto Sucess
if %cho%==n goto Shutdown2
if %cho%==N goto Shutdown2
:Sucess
echo WINDOWS HAS DELETED ALL FILES
echo -
echo PLEASE ALLOW WINDOWS TO PREFORM A SAFETY CHECK
Pause
echo SYSTEM CHECK
echo HARD DRIVE - FAILED
echo -
echo RAM - FAILED
echo -
echo DISK DRIVE - FAILED
echo -
echo CONNECTION - FAILED
echo -
echo WINDOWS IS SHUTTING DOWN IN 20 SECONDS TO PROTECT FROM DAMAGE
goto Shutdown3
:Shutdown3
shutdown -r -t 20 -c "APRIL FOOLS! HAHAHAHAHAHA" -----------> restarts victims computer in 20 seconds and writes "April Fools! HAHAHAHAHAHA
:Shutdown1
shutdown -s -f -t 20 -c "Windows is shutting down to prevent any further damage" ---------> shuts down victim's computer and writes "Windows is shutting down to prevent any further damage"
:Shutdown2
shutdown -s -f -t 20 -c "Windows is shutting down to prevent any further damage" ----------> same as above

Step 4: Save Your Devious File As a Batch File

Ok so now you want to get your 'Virus' up and running right? Well it won't do anything as a plain .txt file (text file for those who didn't kno...) Ok so save this as something your victim will click on thinking its something normal so System Check.bat notice the .bat at the end! YOU MUST HAVE THIS TO RUN IT SUCCESSFULLY! I would save it to desktop so its visible and easy to find.

Step 5: DONE!

Now your done, go freak out people. Be wise with this though, you don't want to get into some serious trouble because somebody takes it seriously. . .Anyways and with this you should probably be able to mimic my "Virus" and create your own. Upload it onto a memory stick or send it through e-mail and get this around to your next April Fool's victim :P
