Windows Defender

[ask100]

Can anyone help me with this problem? When I start Windows this message comes up. I've tried Help & Support but there is no reference to this problem.
This is the message:
'Application failed to initialize 0x800106ba. A problem caused this program's service to stop. To start the service restart your computer or search Help & Support for how to start a service manually.'

do you have any other anti virus software, windows defender can not run if you do have another bit of AV software installed.

Hi, I have AVG running and don't get any problems with Defender. When I get any messages like this with a program I usually go to Add or Remove programs and delete the program. Then reinstall it and that usually works. Always worth a try.

I have Vista with AVG running but have never had this problem before on previous laptops. How do you uninstall Windows Defender?

Hi, not sure what it is called on Vista as I have XP. On XP you go to Add or Remove programs and delete it from there. Then go to the MS site and put it on again. I know that you can do it on Vista as I did it for someone before, just can't remember the name but it's in the control panel.

you can't uninstall defender in vista, you just have to disable it.

Click on the start button, and in the run box type cmd and hit enter..

then in the command prompt that comes up type the following two lines (press enter after each one)

sc config WinDefend start= "disabled"

sc stop WinDefend

That should stop defender and stop it from trying to run at startup.

Tried what you suggested ChuckFickens, but I got the answer:
Open Service FAILED 5:
Access is denied
Any other suggestions?

Log in as an administrator enabled account and do it again.
