Avast has been my preferred AV product since 2006, Hits a Seven Big Drums for all the outstanding bugs to get resolved in stable and beta builds, maybe target a few bugs a month if they have so many it would take them a half a year to fix. Just be hopefully ready for Windows 10 Fall Creators update should be focus right now, then go back and tackle oldest outstanding bug and go from there in my opinion
I may put up with the new threat alerts, as one thing I don't like Defender that much, scans so much slower, doesn't offer same protection as Avast.
Anyhow will see how things go for rest of 2017, and 2018
