False positive or something else?

Hello,

Every time I open my Yahoo Mail the notification that I attached appears. Is this a false positive or a genuine threat?
Both my Chrome and Avast are up to date.

You may report it as possible FP here https://support.avast.com > avast virus lab

So it’s just a false positive?
I don’t understand why this started appearing all of a sudden. I’ve been using Avast for a long time but I haven’t had this kind of problem before, not to mention with Yahoo Mail.

So it's just a false positive?
as i said, report it as[b] possible[/b] FP .... avast lab will/should give you additional info if you report it
