Site is considered untrusted after updating SSL Certificate

system · 2017-06-26T14:28:29.000Z

We changed today our SSL certificate on our Corp website to a new EV SSL Certificate. After we made the change, we started getting the ERR_CERT_AUTHORITY_INVALID error on all Macs that use Avast.
When we disable Web Shield, the certificate is trusted again.
I changed the certificate back to what it used to be, and the site is still untrusted.

Any ideas how to fix it?
