The problem would appear to be caused by incremental definition update version 10534. The definition update service has been taken off-line while the problem update is removed in order to prevent more Managed Antivirus Agents downloading the problem update.
We expect the definition update service to be available again (with a later incremental definition update) within the next hour and will provide further information then.
