How to handle "The Windows Security Center service can't be started."

I continuously receive the following message within the Action Center:

Turn on Windows Security Center service (Important)

When I click on this message I get the error "The Windows Security Center service can't be started."

I am trying to apply the solution at the link support.microsoft.com/en-us/kb/2510301

However the Security Center service is not in the Services list.

I get the following error when I click on the message in the Action Center:



Here is what Services shows in my computer.

Have you scanned for viruses. I once (a year ago) had an infection that disables all security things so i used avast rescue disk to scan and remove it, then i was able to enable them again :)

Finally I found a solution to my problem.

I applied a registry fix to enable the missing Security Center service again.
