Hi,
as I can see with Avast installed I Am no more able to see the relative certificate on websites.
As you can see from the below screen is not printed my SSL but Avast SSL.
So I AM unable to see who has originally relased a certificate to a specific website.
It is not in all websites, only sites (servers) that are using SSL/TLS.
And as I said, there are other ways to check.
A lock in your browser doesn’t mean the site/server/connection is safe.
avast is helping to keep your system safe.
You can check a website’s (server) certificate online (SSLABS is also testing things).
