After being informed that my AVG TuneUp has expired I was led to buy the new software which I did per pay pal. Logging into my account I received the message that my product has expired and i should download the program below. I did that but was told after 5 secs that this software is not compatible with the AVG Software on my pc. I have windows 10.
What do I do?
