过QQ游戏大厅的SX保护
早些时间看郁金香的教程，写过qq游戏练练看的挂，那时候CE附加QQ游戏大厅的时候貌似是没有任何保护的，昨天舍友让做个斗地主的记牌器，但是，我用CE附加的时候，被检测到了，其实不附加也会被检测，所以猜测可能只是检测窗口进程或是模块名称啥的吧，被检测到的时候主程序会退出，但是那个对话框还在，就是那个SX什么什么的，所以如果是QQgame启动了某个线程来检测非法的话，在主程序退出其他线程对象都释放掉的时候，那个检测的线程对象还是存在的（提示SX非法的对话框别关掉！）。借助pt很容易就找到了这个线程。
未开CE前线程状态：
开了CE被检测到后的线程状态：
然后该怎么办就不用说了吧，干掉这个线程就OK了。
若是嫌麻烦每次都要开pt找线程的话，可以写个结束这个模块内线程的程序
