That image isn't an Avast alert window, but your browser (?) blocking an insecure connection, where your browser forces secure https connections.
Though, having checked, first you get the Avast alert (see attached), which stops the connection, followed by the image you posted.
With 157 External links detected, it is possible one of those could impact the main domain.
You can use the - Reporting a Possible False Positive File or Website -

You should get a response in a day or two.
