Hello,
To start the "Security Center" service, use these steps:
* Click Start, Run and type Services.msc
* Double-click "Security Center" service from the listing
* Set the startup type of the service to "Automatic"
* Start the service by clicking the "Start" button in that applet.
Perhaps you have deleted it after a Spybot scan?
So i would recommend to ignore it from future scans.
In order to do so please right-click each in turn, then click "exclude this detection from future scans".
Best regards
