    I have had the same problem, and when i type "net start windefend" in the
    command prompt (black and white screen), I get:

    ----------------------------------------------------------------
    The Windows Defender Service service is starting.
    The Windows Defender Service service could not be started.

    A system error has occurred.

    System error 2 has occurred.

    The system cannot find the file specified.
    -----------------------------------------------------------------

    I found a weird but successful way of solving the issue. I just uninstalled and reinstalled the software by downloading it again from www.microsoft.com

    If in your Vista, your Windows Defender fails to initialize and you get the error message:

    Error Code 0x800106ba Application failed to initialize

    Then you may have to re-register a few related dll files.

    Copy paste each of the following, one after the other in Vista's start menu search bar and hit Enter.

    • regsvr32 wuaueng.dll
    • regsvr32 wucltui.dll
    • regsvr32 softpub.dll
    • regsvr32 wintrust.dll
    • regsvr32 initpki.dll
    • regsvr32 wups.dll
    • regsvr32 wuweb.dll
    • regsvr32 atl.dll
    • regsvr32 mssip32.dll
