As we announced on July 1, 2009, Microsoft is revising its engine mix on Dec. 1, 2009 for the Forefront and Antigen products. This change will allow customers to utilize a set of engines that help optimize detection, while also allowing us to invest in new areas for increasing overall protection for customers.
The AhnLab, CA, and Sophos engines will be retired on Dec. 1, 2009. After December 1st, customers will not receive any updates for these retired engines. In order to make sure your Antigen and Forefront products continue to scan efficiently and effectively for malware, any customers running the AhnLab, CA, or Sophos engines must DISABLE these engines before Dec. 1, 2009 and select from the new set of five engines – Authentium, Kaspersky, Microsoft, Norman, and VirusBuster.
SPECIAL NOTE: Antigen for SharePoint 8.0 and Antigen for Instant Messaging 8.0 customers – In order to gain access to the new engine set and provide optimal protection for your messaging and collaboration environments, please download the Service Pack 1 releases of these products on the MVLS or VLSC site prior to Dec. 1, 2009. The updates for the new engine set will use a new update infrastructure as of Dec. 31, 2009 – the Service Pack 1 releases will allow you to continue to receive updates correctly from their new location.
For more information about Service Pack 1 for Antigen for SharePoint and Antigen for IM, see the following KB article:
- SPECIAL NOTE: Antigen for Exchange 8.0 and Antigen for SMTP Gateways 8.0 customers –These products will end of life on Dec. 31, 2009. Customers must upgrade to Antigen 9.0 SP2 for Exchange before this date, as the product will no longer continue to receive anti-malware updates starting Jan. 1, 2010. With the retirement of the CA, Sophos, and AhnLab engines on Dec. 1, customers running Antigen for Exchange 8.0 or Antigen SMTP Gateways 8.0 will only be protected by the Norman engine. For customers who need to continue using this product between Dec. 1, 2009 and the end-of-life date of Dec. 31, 2009, please contact Forefront Contract Administration for access to the revised engine set.
For more information on upgrading your Antigen for Exchange 8.0 or Antigen for SMTP Gateways 8.0 to Antigen 9.0, see the following KB article:
One of the most important changes in our engine revision strategy is moving to the Cloudmark antispam engine*, which provides 99%+ detection rate and less than 1 in 250,000 false positives (West Coast Labs).
The Mail-Filters SpamCure antispam engine will be retired on Dec. 1, 2009. Customers using Antigen products for antispam protection must upgrade to the latest service pack releases listed below BEFORE DEC. 1, 2009 to maintain their antispam defenses. This is the only way to gain access to the new Cloudmark engine. The service packs can be accessed on the Microsoft MVLS and VLSC sites:
- Antigen for Exchange Server with Antigen Spam Manager 9.0 with SP2
- Antigen for SMTP Gateways with Antigen Spam Manager 9.0 with SP2
For more information on the engine revision strategy, see the Antimalware Engine Notifications and Developments Web page or contact Forefront Contract Administration . Again, we strongly urge all customers to update to the newest service packs before Dec. 1, 2009 to get the full protection benefits of the Forefront and Antigen server products.
*Please note: Customers using Forefront Security for Exchange Server will get access to the Cloudmark engine in the next version release – Forefront Protection 2010 for Exchange Server – scheduled to be available in Q4 CY09.
