Messdage to authorise or block an app appears repeatedly

AVG repeatedly displays this message several times a day regardless of whether I reply Allow or Block. As far as I know, it is a perfectly OK app that converts what I say to a text file though it is handy to be able to turn it on only when I need it rather than to have everything I say recorded. How can I persuade AVG that it’s OK for it to be n all the time? It’s not a major problem.
