On virus detection: no possibility to choose "no action"?

Avast Free Antivirus / Premium Security
1

Situation:
With the File System Shield settings “Actions” set to “Ask”, avast! only offers 3 options when a virus/ suspicious file is detected (see attached screenshot):
Move to Chest; Delete; Block.

Problem:
It is neither possible (a) to choose “no action”, nor (b) can the file easily be added as an exception.

Question:
Is this a “feature” or do I miss how (a) or (b) could be achieved?

I think I have checked all possible settings.

Yes, that is what I would expect.
BTW: I am working with an administrative account (i.e. the “normal” Win7 account), not a restricted account.

Where’s the screenshot…??
Oh, it got lost when reloading the posting. It should be attached here. [UPDATED: “screenshot2”]

Please repost it without the blackening.
