Avast CheckSUR Errors Unable To Correct

I’m using Avast Free. Recently I’ve been experiencing CheckSUR errors regarding Avast. I’ve tried Avast Repair, uninstalling avast with avast clear and reinstalling, sfcfix with script file, nothing works to clear the errors. Your verification images are unreadable and your listen to letters doesn’t work
