No Forum mails

How can i stop receiving Info Mails from forum.avast.com ?

Can you give an example of what it is that you are receiving ?
Not detailed, general subject matter.

I get very few notifications and I post a lot.

When you post I believe you should get the option to be Notified of replies, I click No and never yes. But I suspect this isn’t what you are on about. As your topic history is a little old but you could check your old posts MyMessages and deselect any that might have Notify of replies.

This is why I asked what is the subject of the emails.

The Forum is in the process of being upgraded and I have had two Forum related posts (but I doubt it would be that).

Go to your Profile>Preferences>Emails and change to “never”.
Also, scroll down and check “Activity Summary” item is also unticked.
