We even called Avast and we were told they can't help us and we need to submit a ticket. We said we think it is due to the update and its a false positive and they said then you can write a exclude statement for it. Since it is flagging tons of files, that would be a endless battle. If you guys have not created a ticket yet, I would suggest putting one in so we can have extra pressure for them to fix the latest batch of updates.
