How does avast detect the file? Is it evo-gen?

Have you entered the file into the global exclusions?

Your best bet would be to create a folder for the files and exclude them in global exclusions (excludes shields and on demand scans)

avast UI > Settings > Antivirus > [scroll down] to exclusions > set them as you wish.

That being said, if you’ve done a clean install, the actions should work. I’m not sure if the actions work with the evo-gen detections though.
