About the email Protector!

Good morning. I have had the premium package for at least two years and the email protector. I noticed that even spam emails are marked with a green flag by Avast, which means they have passed the check successfully. All these phishing emails were about fraud to steal personal banking information, or information that someone would give to the tax office, and the pretext was that they would refund my taxes. Of course, I never opened any such link fortunately because I know most of these scams and not because Avast protected me. Could the problem be related to the Greek language (or foreign languages ​​in general) to some extent? Because I am Greek and of course the spam is mainly in Greek. The spelling and grammatical errors made in these fake emails are clear to someone who speaks a language well, but that’s definitely not the problem because the spam message is perfectly translatable allways. And there is the fact that the Greek Tax Office (or any real bank), does not have these types of email addresses! It’s not too difficult for the system to ‘learn’ which are the authentic bank or government email addresses, and if you use AI to read the emails then you know that the content has nothing to do with the sender. I think! Correct me if I’m wrong, but so far the email protector is doing more harm than good, because if I didn’t know what I know and had trusted Avast’s green flag, I would have considered these emails to be genuine and then I would have had a really serious problem, and in this case who would take responsibility?. If a security product is not complete, therefore not safe, it is forbidden to place it on the market. Please patch or retire the app until it works properly.
Thank you.
