Hotfix rollup 3 for Forefront Security for Exchange Server SP2 and hotfix rollup 3 for Forefront Security for SharePoint SP3 are now available

On behalf of the Forefront Server Protection team at Microsoft, I am pleased to announce the release of Forefront Security for Exchange Server (FSE) SP2 Rollup 3 and Forefront Security for SharePoint (FSSP) SP3 Rollup 3.


On October 8th, 2010 Microsoft shipped both builds to address a performance issue with version 8 of the Kaspersky antivirus engine.


For a detailed description of the updates please see the following Knowledge Base articles:

As the installer runs, server service restarts may be necessary, so please plan accordingly when applying this hotfix rollup.

    Hi Pete,

    Incremental updates for the Kasperksy 8 engine are not working correctly.  This is a known issue and will be remediated automatically through the engine update process within the next week.

    Thankk You,

    Rob M.

    This was installed by MS Update on the 1/26/2011 on our Exchange server.  Since that time, the Kapersky update downloads the entire engine anytime the signature files are updated and this file appears to be a huge file.  I thought one of the reasons for going to Kapersky 8 was the reduction in signature file size.  We have seen a significant increase in our Internet bandwidth usage since our Forefront for Exchange 10.0 was upgraded/updated.
