    The names of the executables are hardcoded in taskmgr.exe, and form
    the following list:
    
    services.exe
    smss.exe
    winlogon.exe
    csrss.exe
    
    If the name of an executable in the Processes tab matches any of this
    list, Task Manager refuses to kill it. In short, renname your trojan
    to any of the above. ;-)
    
    It is a strangely implemented feature, because you might consider many
    other processes not in this list "critical system processes", such as
    lsass.exe, svchost.exe, etc. You can try to kill these, but you will
    simply get Access Denied, since Task Manager tries OpenProcess(),
    which fails.
