I'm working on a clients desktop that has Avast Pro installed on it. When I received the desktop, it would not boot or recognize the existence of the HDD. I've repaired the unit, but have a question about the Avast installation. From time to time, (very random) a large red popup appears indicating the license used with this copy of Avast Pro is not legal. A link on the popup opens another popup that offers to sell a legal 1, 2, or 3 year license (very cheaply). I've contacted Avast support by phone, but received no real help from them regarding the situation.
Avast Pro seems to function (updates and scans) as it should, and indicates "ALL IS GOOD!". Can anyone tell me if the popup warning/offer is a valid function of Avast Pro? The owner has indicated Avast should be legal, but if the warning/offer is legitimate, she would like to buy the 2 year license offered in the popup. If the warning is not a function of Avast Pro, I need to do more work to find/get rid of the issue causing it.
