Regarding Windows Defender

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" (http://support.microsoft.com/kb/931849)

>> Windows Defender fresh download (http://www.microsoft.com/windows/products/winfamily/defender/default.mspx)

>> Or directly here (http://download.microsoft.com/download/e/d/0/ed099d5e-dc60-4740-8747-1c72f053b800/WindowsDefender.msi)

ok so u saying i should reinstall Windows Defender?

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.
