    Vista Security and Windows Defender will not start


    I recently had a Trojan and Symantec anti virus removed it. However when
    I uninstalled Symantec (I wanted to place in another anti-virus) Windows
    Security became unavailable. If I go to Control Panel > Security nothing
    happens. When I try to access Windows Defender then I immediately get a
    blue error screen. Now whenever I open up Internet Explorer sometimes
    strange noises start to happen as if I'm watching a video. (goes away
    when IE closes) making me think Symantec was not successful. Also I am
    running Vista Home Premium.

    It sounds like Windows Management Instrumentation (WMI)has been damaged
    by the combination of malware and Symantec.
    First, see if you can run this security software removal tool:
    AppRemover
    http://www.technibble.com/appremover...l-of-the-week/

    If you can, then remove all vestiges of Symantec and any other installed
    antivirus.

    If not or if you could remove Symantec with the aforementioned tool,
    open an Elevated Command Prompt ( Start orb > in the Start search field
    type in cmd > *right* click cmd.exe and choose 'Run as administrator' >
    if no password is used click the Continue button; if one is used enter
    it and then click OK.

    At the Elevated prompt, type in the below and then press Enter
    (Note the space between the " t " and the slash /)

    winmgmt /verifyrepository

    If WMI reports that it's in an inconsistent state try running the below
    command

    winmgmt /salvagerepository

    You may have to run it twice. Reboot afterwards and then run the
    verifyrepository command again to see if WMI was salvaged.
