You mean this current account that I’m using right now? Like I said, it was just created today when I tried to log in with an email and password that I never used to register here. And yes, by “this site” I mean this forum.

I don’t think I ever registered on the “old” Avast forum, I don’t even remember an old one since I only registered here fairly recently (march of this year) with my original account.

Maybe that “linking” you mentioned has something to do with it. I used the same email and password to log in here that I used years ago when I registered Avast, but I really don’t know what exactly I registered back then, I only know I did it directly via the antivirus program, I don’t remember using a website for that.
