When a Comprehensive Risk Report is generated by the Symantec Endpoint Protection Manager (SEPM), the "Discovered" data for certain risks under the report's "New Risks Detected in the Network" segment lists the date discovered as 12/31/1969.
Risk name Category / Type Discovered XM.Laroux.GA 1 / Viral (Macro) 12/31/1969
The Time Zone that is configured for the server may not match GMT. Attempting to compensate and display accurate data for the configured time zone, the SEPM incorrectly processes the discovery date of the risk.
This problem is fixed in Symantec Endpoint Protection 11 Release Update 7 (SEP 11 RU7). Upgrade to the latest available release of SEP to take advantage of this fix and many other enhancements and improvements.
