Some file can't scan.

Hello,
This is first time here.
Avast! Thanks for the great program.
I have pro version, I was upgrade and I have curious one thing.
When I scan my comp. There in one file can’t scanned.
Scan result page says “Can’t scan password protection”.
File name is (Ad-Aware default.ask). This is Lavasoft(Adaware) file.
I know that this is not harmful. Also, this file contains 41 files, may be zip file something, not sure.

C:\Program Files\Lavasoft\Ad-Aware SE Personal\Skins\Ad-Aware default.ask

I think this is not only my problem, I read Avast Reviews at download.com.
Some people mention about this problem.
So, is this impossible to scan?
I just curious.
Thank you very much for your advice.

Sorry, for bad English.
