I have not seen this before so I thought I would mention it and it will probably eventually take care of itself on the next update but my version 2 mirror and clients are on virus signatures database 5723 and version 3+ mirror and clients are still on 5722. The DB version located in the General tab under the server options indicates 5723. The threat center web site (http://www.eset.com/threat-center) indicates 5722. The update.ver file under the version 2 mirror indicates 5723 and the update.ver file for version 3+ shows 5722. I cleared the update cache and initiated an update but there is no change.
