    Hi everyone,

    My laptop was recently infected with a virus that hijacked my browser and started this wau.exe file that displays this fake Windows Defender scan that keeps popping up when I access the internet. I was able to remove the infection using Malwarebytes but afterwards, every time I start up the computer, I get this message:

    Windows Defender
    Application failed to initialize: 0x80070006. The handle is invalid.

    I can't start it manually and I don't know if this is because the virus turned it off or removed something from defender.

    I use Windows Vista Home Edition

    Please advise me on how I might be able to correct this problem.

    Thank you so much for your help. It is greatly appreciated!!!

    I uninstalled Windows Defender after having aquired a virus that mimicked Windows Defender which took over my computer. I had to go into safe mode to run a malware scan and quarrantine the SOB. Then proceded to uninstal the actual Windows Defender.

    Since then, I had the same error message upon each and every start up, and I searched online for a resolution.

    Microsoft asks you to reinstall Windows Defender (of course) but all you really need to do is this to make that error message go away is this:

    Click Start Menu button
    Type 'msconfig' in the search area
    Click Enter

    A system configuration window will pop up. The first tab is General. There is a section called Selective Startup. Uncheck all and click on apply.

    Reboot your computer and enjoy your PC once again :) You will have to open your programs manually from then on, but it's better not to have unecessary programs running upon start up, anyway. IMHO...
