If you don't already have a subscription to OneCare, you won't be able to activate it. 0014 indicates a connectivity problem and it can certainly be caused by an infection.
If you are in North America, you can call 866-727-2338 for help with virus and spyware infections. See http://www.microsoft.com/protect/support/default.mspx for details. For international information, see your local subsidiary Support site.
