Hi hlhl, I’m aware about the risk to uninstall the app but i could still fonctionning with Microsoft Defender (for information I’m not paid by Microsoft lol) by the way I tried before give up another solution, I uninstalled Avast and installed the free version on Proton VPN to connect a server in Netherland (in my case and again I’m not paid by Proton) after I reinstalled Avast with the offline file suggested above, I make a personal install with just the minimum install “file shield” and Behavior Shield” (I don’t know if it make a difference if I install Avast normally but I always installed the app like that). After the installation all seems good, So I suppose that the issue is in the Ad part of the code of the app but i’m not an expert. So if the people who experience this issue can confirm that this workarround helped you and if you’re living in France like me let us know it can also help the Avast support to find a solution quickly. Have a good day.
