Hi is there a way to detect processes which don't show up in the Task
Manager list? The reason I suspect such processes exist is because
1) I have suspicion my system has been hacked due to weird internet
behavior
2) When I shut-down Win2K I briefly get a dialog box saying
"Closing You Should Not See Me", and another one "Closing WinVNC tray
icon"

I can't see "You should not see me" process nor "WinVNC" in the
process list, nor is there an icon for WinVNC in my tray.
