    Whilst true, this is a bit like answering "chicken" when asked if the
    ocean might be blue.

    The .EXE you are talking about is installed in the "system" directory.
    It should _not_ be in the Windows installation directory as the OP
    clearly stated was the case here. The mystery file also has the hidden
    file attribute set -- another thing we would not expect of the "normal"
    services.exe file.

    Whilst the concluding sentence is a reasonable position to hold, it is
    largely not relevant to the foregoing.

    Not much.

    You see, filenames alone are seldom useful _AND NEVER SUFFICIENT_ for
    diagnosing malware, yet that is what you have tried to do.
