GuateGT I am not sure why you're seeing that message is showing via AVG. Your site has an active SSL certificate and is serving https versions: https://pubdash.ezoic.com/settings/privacy/ssl
It seems the error is actually because 'the SSL certificate is not trusted'. We can't comment on why that message would show and you'd need to ask AVG to clarify why that is further. I've never personally encountered this on another single Ezoic site.
