Microsoft Security Essentials stops after launch
I have Windows 7 64 bit, and have been running Microsoft Security Essentials for months.
Yesterday, I got a message that Windows Security Center service would not start. Also, the tray icon for Microsoft Security Essentials disappeared from my system tray.
The Security Center Service message no longer appears, but I cannot get Microsoft Security Essentials to work. When I click to start the program, I see the startup screen, and then it immediately disappears, and its icon appears in red in my system tray. When I mounse over to it, it disappears.
I tried starting the service (services.msc) but I can't get the software to work.
