一个PsSetLoadImageNotifyRoutine回调内核注入DLL，支持xp ~ win7源码
最近看sudimi大牛写的《一个有趣的内核注DLL的sys》文章，确实很有趣，可惜没开源，俺也写个，把完整代码也贴上来了，欢迎拍砖。
安装驱动，打开dbgview.exe，注入mydll.dll！！
VOID Start (
IN PUNICODE_STRING FullImageName,
IN HANDLE ProcessId, // where image is mapped
IN PIMAGE_INFO ImageInfo
)

int nImportDllCount = 0;
int size;
// PID改变时，可以说明已经注入DLL了。

BOOLEAN bAttached = FALSE;
//_asm int 3;
if(g_psaveDes!= NULL)

bAttached = TRUE;
}
//

and eax, not 10000h;

// 注入进程没退出。

/* 分配导出函数的进程地址空间。
