    RE: Hidden Process

    Hi Pony,

    I'm not sure how do you define a process is "hidden". Anyway, following
    information might be helpful for your reference:

    1) Use Process.GetProc ess() to get all running processes on current system.

    2) You can iterate in the process list to find your target process (which
    you want to kill)

    3) A Process have a method named "Kill()" which can be used to kill it
    immediately.

    Let me know if you need further information.

      RE: Hidden Process

      Hi Pony,

      For such hidden process created by a rootkit
      (http://en.wikipedia.org/wiki/Rootkit, http://www.rootkit.com), it will not
      be listed by normal process api such as .NET Process class. To understand
      why it's not listed, you need to first understand some information how a
      process can be hidden from normal tool/API such as task manager.

      Win32 Kernel Rootkits can hide running processes from users using
      techniques like Kernel Native API Hooking, or by directly unlinking the
      process's EPROCESS entry from ActiveProcessLi nks. Such techniques are very
      effective in hiding processes, and are very difficult to detect with
      user-mode tools.

      To detect such hidden process, you will also need some kernel-mode driver
      or api to do that, such as code from
      http://www.security.org.sg/code/kproccheck.html; http://www.rootkit.com is
      a good resource on RootKit and various tools to detect rootkit.

      Hope this helps.
