This area is for McAfee Firewall Enterprise running on an appliance. It sounds to me like you are running McAfee software on your home PC, such as McAfee Antivirus. Please either report the exact product you are using so we can point you to the correct forum, or try and find the correct forum to post on.
While we wait for you to say which product can you post a pic of the message?
Also try restoring to a point prior to that point where it all happened.
