WallFlip.exe false postive

I use avast! 5.0.396 to scan these two files 1.exe and WallFlip.exe.
avast! regarded them as viruses.
Then I sended these suspicious files to virus@avast.com, but no response.
Then I sended these suspicious files to Avira GmbH.
After careful analysis, Avira said there is no virulent component in these two files.
I think this is the false postive of avast!
I upload these two files to MediaFire.

1.exe

WallFlip.exe

Please fix the problem of false postive.
Thanks!
