I am getting the following error, "Application failed to initialize: 0x800106ba. A problem caused Windows Defender Service to stop.To start the service, restart your computer or search Help and Support on how to start a service manually" Also I have Avira Premium Security Suite, my OS is Windows XP SP3 32-bit with lastest updates installed, & of course my Avira Premium Security Suite & Windows Defender has the lastest updates installed as well.
>> Error message when you run Windows Defender: "Error Code 0x800106ba" >> Windows Defender fresh download >> Or directly here
Sometimes when a program is not working right or behaves abnormally a quick fix would be to uninstall it and reinstall again. I'm not sure but you may have to reboot after uninstalling.
I see then WinXPert, thanks I just did that, I will run Windows Defender to see if this fix this problem, & let u know if it work, well I decided to download the update definitions instead, & install it so thanks.
