Pop-up after D/L from Inet all of a sudden?

In the last 2 weeks or so, I started getting AVAST open up after I d/l a file from the web? This didn’t happen before, and I don’t think I changed anything? I’ve searched high and low in the options for a setting that controls this but can’t find any?

Suggestions?

Thanks, Irv Spalten
