NIS 08 Scanner Problem?

This was a problem but not any more. But when i ran a a full system scan nothing was detected but when i done quick scan to a certain directory "Adware.Gen" was detected. So why wasn't it detected in a full scan.

 

At that time i had Windows Vista Service Pack 1 with NIS 08.
