Dont know if any of you have been affected by this, but some sort of Avast mobile update is flagging both our free apps as Trojans, neither app has been updated in a while and no issues reported, in the last day, half the posts are saying apps are showing up as Trojan alerts with Avast. There is a discussion going on about this on the Avast forums already.

If this is affecting you please let them know so they hurry it up with an update.
