Android, AVAST sync to gmail

Hi guys. On my android phone theres suddenly af avast account. When im in accounts in settings it wont let med remove it. Is there a easy fix? Kind regards

Did you install Avast?

No. Im having this strange expirience. It was suddenly there. Just as you would have a google or microsoft, whatapp linked with your email. In my case my gmail. I have tried and tried to find a solution nothing worked. Today I tried to install Avast and then a second “link” came up in the account administration on my phone. It went away uninstalling the app again. But the other still there. The really stange thing is. I got a brand new phone, yesterday. Got it set up with a completely different email from gmail. Got through the set up of the phone. Perfect no strange Avast sync, link or what it would be called. I the add my old email adress, because I want to check the gmail together with my new on. And everything was fine until today. Somehow Avast is now figuring on my new phone when I go to account administration. It blows my mind. When i try to remove it, its says the same thing. “This change is not allowed by my administrator” What… How would adding a gmail mean I would get a Avast…

Is there something im missing?
