The definition update service is now available again. Those Managed Antivirus Agents that downloaded the problem update will now fall back and download a full definition update (and then the latest three incremental definition updates).
This may result in some additional network traffic while the full definition update is downloaded (especially where a site concentrator is not employed) and for this inconvenience we apologize. However, there is no additional customer action required.
