Trojan.Bankpatch.C!inf - Certified Definitions

A few questions:

 

01. Why was this Detection just Added on February 04, 2009 to the Certified Definitions when it was Discovered on August 18, 2008?

 

02. Why did the Weekly Certified Definitions get Released on August 19, 2008, and yet the Daily ones only got Released on February 04, 2009?
