I have been getting the Chrome pop-ups too and I have never had Chrome installed. Also, the tip to tell Avast not to use Chrome by default did not help. It’s annoying but not too big of a deal. Maybe Avast will eventually fix it so us non Chrome users won’t get offered tips for Chrome.
@DavidR,
I had the computer on all night. In the morning I right clicked the avast icon and selected show last popup message. Is was the update popup and it not longer had the Google tip button. Hopefully your suggestion has fixed the problem. I will keep an eye on it. Thanks again for the help.
