As I posted on Beta board ( http://forum.avast.com/index.php?topic=141845.msg1036612#msg1036612 ), this problem continues in 2014.9.0.2011.
“Report the file as a false positive” of WebShield does not work in case that the file is included in an installer, a SFX file or an archive file.

I tested it at EICAR site http://www.eicar.org/download/eicar_com.zip .
