The aplications simply readds itself to the registry even after multiple deletes.
I have tried to disable this “feature” from their own launcher, quarantine it, disable it with ccleaner, set the whole folder to read-only after deleting the file.
It reappears after launching the game, thats why i search for a way to auto delete it after closing the game.
Sounds like it is either created or downloaded if you start the game.
If it is downloaded, perhaps you can block the download in the hosts file or firewall.
If it is created, there is nothing you can do about it unless the game has a switch that can do so.
Anyway, this has nothing to do with avast.
Ask the developer of the game.
