Hi Werner,
That is a reassuring thought anyway. Again thanks for the avast shields, the best innovative protection layer of the avast solution.
What a user can do however is use this online scanner:

What the advantage of the webshield check is that it will check and work on/function with all varieties of 2D codes (EZcode, Beetagg, Shotcode, SimpleAct and NeoMedia etc.). Users with a smartphone should be aware not to scan suspicious QR codes that were applied (sticked) over existing QR codes, so watch out on the bus, on the airfield, in the school lobby and check first...well the avast webshield again will protect...
