Your security suite does not replace the functionality of Windows Security
Center. This Center provides an UI to Windows's security features, and
monitors all security applications running on your system. By disabling it,
you will no longer be notified if there's anything wrong with your firewall,
AV, AS, updates and other security settings. That's why I called it a bad
idea.
