This is from the recent message from Avast:
I'm very sorry that the signed file was blocked. The process is semi automatic based on virus definitions. If a page or file is suspicious, detection is created based on definitions. If this is a false positive detection, you need to report the detection as you did. Subsequently, the detection is reviewed manually by our specialists, who will determine whether the detection is correct or false. Even if it is a false detection, the detection is manually changed (turned off).
It's been 2022. Soon spaceships of earthlings will traverse the vast expanses of the Milky Way, and anti-virus companies will continue to manually add new legit software releases to exceptions, and require emailing a file no larger than 10 mb in an archive with the password "infected". :)
