I use Avast Free Antivirus on Windows 10 pro, the problem I am having is - 1. I cannot change my IPV4 DNS settings without uninstalling Avast, when I have changed my IPV4 DNS settings for my Smart DNS Proxy servers, then re-installed Avast Free antivirus, I can no longer use Microsoft Office Outlook 2013 to send and receive my Orange.fr email.
I have looked at all of my settings and cannot find where to swich off the secure DNS features. I am using version 18.3.3333 (build 18.3.3860.316)
