I have Windows Live OneCare and Windows Defender installed on this computer. Everyday around 8am and 2pm, Windows Defender disables itself, and shuts down my real-time protection. I have to click on Start, All Programs and then click on WinDef. When I do this, I get a box that says this program has been disabled. There is a blue link that you click to re-enable it. Like I said, this happens to me twice a day. If I restart my computer with Windows Defender enabled, I get an error message upon startup with an error code, "0x800106ba." I've done some research on this error code, and I've done some trial and error troubleshooting of my own. Re-registering certain DLL files, going to Run, typing cmd, and then Net start windefend ...none of these worked for me...I can't really say that to all of them. The one where I had to re-register my DLL files, I couldn't finish. It asked me to uninstall Windows Defender, re-register the associated DLL files I guess, and then re-download defender. I did all of that, and I got stuck because it said I have OneCare installed, and it asked me to remove that program before proceeding. When I had OneCare beta, it asked me to download Windows Defender beta in order to get spyware protection. Did they implement spyware protection in OneCare now? Is that what's causing the conflict?
