If I install codeSHOW from the Windows 8 Store, or if I build the code myself and run the JS Windows App or even the Windows Phone app, Avast! intercepts it with a malware threat detection.
Edit: The Avast! detail specifically shows:
URL: https://codeshow.azure-mobile.net
Infection: URL:Mal
Process: C:\Windows\System32\WWAHost.exe
If I go to https://codeshow.azure-mobile.net in my browser I get the same threat detection.
