Getting connection is not private error only in Edge

[ies_ebox]

Just installed Avast Premium on my Windows 10 Pro Laptop and started to have this issue.
Previously I was using Avast Free without a problem.

The problem I am having is only in MS Edge and not in Chrome.

When I go most of my financial sites (bank, credit card, etc) the site does not load and I get a message "Your connection is not private. Attackers may be trying to steal your information" net:err_cert_invalid.

I also can get the error on part of a site, so I can go t bloomingdales.com, but if I try to pay my monthly bill I get the error.

The site could be a bookmarked or cached site or a totally new site I have never been to before.

Not using Avast Firewall.
If I disable Core Shields the problem goes away.

Of course problem goes away when you disable your protection. 

No protection, no alerts.

Are you using Avast Secure Browser as your default browser?

The issue only happens in Edge - Does not happen chrome.
Chrome is my default browser, Avast secure browser NOT installed.

Please attach a screenshot of Edge error.
