Avast Shield Blocking Access

Using Avast Pro 2015. For the last few days Avast Shield has been blocking access to a website. Popup reads: Avast Shield blocked access because certificate invalid ssl278365.cloudflaressl.com. Added this url to the exclusion list in web shield but access continues to be blocked.

Any solutions appreciated. Thank you.

A side comment: Avast years ago ran quietly in the background & didn’t affect speed. Now seems to be very heavy handed with all the add ons, getting slower with each upgrade.
