Log-in Problems

I can't see that my last reply went through OK, so here it is again.
'How did I narrow it down to AVG?"
Because I had a look at the Certificate and it states:
Issued to:      *.au.Syrahost.com
Issued by:     AVG Web/Mail Shield Root

I just disabled AVG Email Shield, and it is now happening only when I log on the first time.   When I closed down and logged in again, it didn't come up again  -  I tried that a couple of times, and it's gone now.  But I cannot be without "Email Shield" !!!   Please advise ASAP.

Hello, Robyn.
May I know how did you narrow this down to AVG? Please disable AVG Email scanner temporarily and check if the issue is resolved. Open AVG Internet Secruity, click on Menu -> Settings -> Components -> Email scanner. Toggle the On/Off slider against it to disable the component.

Every single time I try to log into Outlook 2016 I get the following pop-up message:   The server you are connected to is using a security certificate that cannot be verified.  The target principal name is incorrect.  (View Certificate)  Do you want to continue using this server ?  Yes/No".
It's really annoying, this comes up every time I go to open Outlook 2016.   I've just had AVG Internet Security installed.  Can anyone help ?   (ALSO  -  FOR AVG'S INFORMATION:   I tried to send this on-line through your web page Contacts, but it won't 'load'  -  that circle 'thing' keeps whizzing around and around, but does nothing.   I've been trying for about 30 minutes !).

Robyn, could you provide a screenshot (http://avgclick.me/getscreenshot) of the message if you want to install the certificate? Click on 'Answer' & then click on the 'Image' [mountain symbol] & follow the instructions.
