My firewall turned off and I couldn't turn it back on. I reinstalled OneCare using the cleanup tool and then a fresh install. Now my PC shows up twice: one in good status with firewall working, the other shows OneCare Circle "At Risk" and is completely frozen out to access except for "Remove this PC" option. Problem is it won't let me remove the duplicate PC and the system tray icon is showing red because of the duplicate PC "Urgent: Turn on Firewall" message. How do I remove the duplicate PC from my OneCare Circle? When I try to remove it, I get a mesaage stating: "An error is preventing Onecare from performing this action. Please restart your computer and try again. If the problem still occurs, contact the Help Center."
