Avast resporting my app as malware

Since yesterday my app "Geocachers On The Move" is reported as Malware (FakeInst-AFO) by Avast on Android 5. Does anyone recognise this phenomenon? I have already reported this to as false to Avast. 
But can anyone advise me on what I can do further?



Thanks for responding to Avast.   If you search the forum you'll see that some other App Inventor users have run into Avast reporting false positives as malware.
It seems to be an issue with more than App Inventor.  You may have already seen this:
