A new version of the Norman engine was released through the Forefront Server Security Rapid Update system on March 26, 2009. The Norman update package was made available for download at approximately 8:30 am EST on that day.
This is the first new Norman engine release since we rolled back the 184.108.40.206 engine on February 26, 2009 in response to the increase in memory usage by that engine version (see blog entry Update on the recent Norman antivirus engine issue). Since then and up until March 26, we have been distributing the Norman 220.127.116.11 engine and providing daily signature updates for that version.
The Norman 18.104.22.168 engine that was released on March 26, 2009 incorporates several important changes and does so in a way that does not result in a significant increase in memory usage requirements.
§ The engine initialization time has been decreased significantly. In our test environments, we do not see timeouts or delayed load times by the Norman engine.
§ The root cause of many drwatson reports and intermittent Norman engine crashes on engine unload has been resolved in the 22.214.171.124 engine.
