You display a basic misunderstanding of Windows Security Center (WSC).
WSC - an integral part of Windows which cannot be disabled - monitors the
status of your security software. For example, if you have chosen to install
a third party firewall, as I have, WSC will monitor the status of that
firewall. This is true so long as the firewall is compatible with WSC, as
all the major firewalls are by now.
Similarly, WSC monitors the status of your antivirus software and the
availability of updates from Windows Update. For example, I have WSC setup
to notify me when a security update is available at Windows Update.
Since I keep my firewall and antivirus software up to date, the only contact
I ever have with WSC is when the little yellow icon shows up in my tray to
let me know that a security update is available. If not for that, I could
easily forget that WSC even exists.
