I'm unable to find ANY firmware type errors. Webroot should offer support for their Anitvirus with Spysweeper, if the subscription is up-to-date and paid for. Their telephone numbers and online support information can be found below.

You can also make use of their Knowledge Base. Make sure to enter the correct name of the error. Some have made reference to a Framework 966 error. Double-check it and see if the below offers any help.
