判断代码是否运行在某个进程的上下文中 
   VOID DisplayItsProcessName()
{
   PEPROCESS pEProcess = PsGetCurrentProcess();
   PTSTR ProcessName = (PTSTR)((ULONG)pEProcess + 0x174);   //X64位下应该+0x2e0
   KdPrint(("%s
",ProcessName));
}

断链隐藏进程  
利用       ActiveProcessLinks 双向链表断链

枚举进程模块 

VadRoot          利用的是红黑树实现内存模块管理
