Avast keeps detecting threats every few seconds.

So this is my first post here, So I apologize if its in the wrong section.
Yesterday when I opened Chrome avast kept poping up, saying it has detected a threat, from a URL:MAL type. The thing is , Im not even opening new sites or anything, I just sit on one page and occasionally it just appears and its getting really annoying.

I’ve reinstalled Avast - same problem.
I’ve reinstalled Google Chrome - same problem.
Changed to Mozilla… same problem.

Is there any fix to this? The obvious one is for me to just scan with Avast, and will do so right now. Will post again if it doesn’t fix anything, but please tell me if there is a specific solution to this.
