Windows Defender

I use Microsoft Security Essentials and Windows Firewall so I thought I would use Windows Defender as well. According to my computer it is not running. When I click on it to start I receive a message "This program is turned off". "If you would like to use this program click here to turn it on". If I click on it nothing happens. All I get is the spinning wheel that doesn't stop. If I check in "services" its startup type is listed as "manual" and its "status" is blank. I tried resetting it to automatic and rebooted but when I come back it hasn't changed. Am I doing something wrong?

Microsoft Security Essentials has superseded Windows Defender and the MSSE install turns Defender off. It is most likely to create problems running them simultaneously.

Thank you for the reply
