And the problem is???
As has been explained multiple times on this board, there are applications that encrypt some of their files. (eg: spybot, ad-aware, jvm etc)
The thing you see is perfectly normal and is no reason to worry about. Avast (nor any other av) can scan files that are pw protected or encrytpted in a way the av doesn’t know.
If you want to know if the file(s) that are not scanned are harmfull or not, have a look at their location. That already will give you a good clue.
