Hi Plz couls someone help me, when I start my computer, as soon as windows is booted up, I get the following error message:

Application failed to initialize: 0x800106ba, A problem caused Windows Defender Service to stop. To start the service, restart your computer or search Help & Support on how to start a service manually.

Now I hacew tried a re-boot, and I can't find any help and support, Someone plz help.

It's been doing this since the start of the year, hasn't it?

The beta has expired. Uninstall it then download and install the latest version from the microsoft website.

I will give that a try Thanks

Yep, this is the answer to your question.

I use Ad Aware Personal and run it once a week to get rid of spyware, download it from from here:

File Hippo - Download Free Software

This actually happend on some non-beta installs too, it was a dodgy update via windows update that caused the problem, was the same fix to solve it though!
