 New data files added to the virus definitions on April 9, 2003 

Situation:
Symantec Security Response anticipates releasing version 2003.1 of 
the AV engine in the time period between April 30, 2003 and May 14, 2003 
inclusive.  The AV engine is the scanning and repair component within 
the virus definitions.

Solution:
In preparation for this release, several new data files will be added 
to the virus definitions starting on April 9, 2003, US Pacific time. 
These data files will not be used by the existing AV engines. There 
will be no functionality changes until the new engines themselves are 
released.
