Avast Shield is blocking QNAP NAS connection

[shaw600]

Hi

After a recent update Avast Shield is blocking Qfinder Pro connection to my NAS.

I can access the NAS if I disable the shield but I never had this issue before.

I have had a quick look through the settings but I can't seem to find a solution, please help.

Set the Avast Firewall to private mode and reboot.
