Windows Defender

[Panic]

In Control Panel I clicked on Windows Defender. It showed it was turned OFF
with a highlight to turn it ON. I click on that and it shows the blue
activity spiral icon but it just times out without installing. I have
Windows 7 Home Premium, 64-bit. My Windows 7 firewall, anti-virus, and
spyware are all active and work fine. What am I missing without Windows
Defender being ON?

If believe that if you have another firewall installed (Norton, MacAfee)
those programs may turn off defender by default as it is surplus to
requirements

hope that helps

What anti-virus program do you have installed? Several of them
(Windows Security Essentials, for example) turn Defender off, because
its capabilities are built into them.
