If you go into Start > Control Panel > Security Center > Resources (on the left hand side of the window ? expand if necessary) > click "Change the way Security Center alerts me". This brings up an "Alert Setting" window.

There are three possible alerts:

• Firewall
  Alert me if my computer might be at risk because of my firewall settings
• Automatic Updates
  Alert me if my computer might be at risk because of my Automatic Updates settings
• Virus Protection
  Alert me if my computer might be at risk because of my virus protection software settings

I believe that you will find that the first and third items are unchecked. This is the cause of the following Spybot detections:


Code:

Windows Security Center.FirewallDisableNotify: Settings HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\FirewallDisableNotify!=dword:0Windows Security Center.AntiVirusDisableNotify: Settings HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\AntiVirusDisableNotify!=dword:0

When the McAfee SecurityCenter is optionally selected as the default security center, it turns off these alerts within the Windows Security Center so that the Windows Security Center will no longer notify you if your firewall and/or antivirus are disabled. As indicated by spybotsandra, this is not a threat as long as McAfee SecurityCenter is running. However, from my perspective, McAfee has done a disservice to their users by not informing them that by selecting the McAfee SecurityCenter as the default Security Center these Windows Security Center alerts will be turned off. If you were to abandon McAfee products in the future they have left the features of the Windows Security Center in a compromised condition. I personally do not have my McAfee SecurityCenter running as the default security center.
