Commercial materials flow away?

Seams like CAV doesn’t understand WinRAR SFX files. At least not all. Some SFX archives of mine, CAV considers as suspicious or even infected. I’m absolutely sure there are NO viruses. Some files may be commercial.
So is there any possibility by default those files are sent out without notifying me? We all know every lock (encryption) can be broken. Question is rather serious for me and for other people as I can not use or recommend a “black-boxed” product. I know there are options to allow or disallow but by default all these check box SHOULD be disabled.
What do you think?
