Windows Defender keeps getting turned off, particularly when I shut down.

I am also running Microsoft Security Essentials.

Does Microsoft Security Essentials turn off Windows Defender, or is there some other problem?

Windows Defender is configured to start automatically on startup. I am running a Dell laptop, OS Windows 7 Home Premium, SP1, 64 bit, on High Performance power setting.

Fair enough. If I don't need it, there's no point in running it, is there? Thanks!

It is not a complete replacement but it is still better. It should only be enabled when there is something that mse can't do but Windows Defender can.

Incorrect. MSE completely supercedes and replaces Windows Defender if it's installed.
