Windows 10: McAfee SECURE Safe Browsing shows Gmail doesn't have a valid SSL?

I'm not sure where to ask this, so please move to the correct place if needed. I'm curious as to the security of Gmail. I have the extension McAfee SECURE Safe Browsing from the Chrome Store, and when checking it on Gmail it shows No SSL. Why is that? I checked other email providers like Outlook and Yahoo, and both show Valid SSL. Can someone please explain this? Here are two examples. Gmail shows No SSL, and Yahoo shows Valid SSL. Is Gmail not as safe/secure? Why do some show Valid SSL and some do not even though they both start the same with HTTPS?

EDIT on findings: I've done some other checks on other Google pages, and they show Valid SSL (Checked Google+ and Google search). It seems only Gmail shows No SSL.

Will McAfee Live Safe interfere with Windows Defender?

Have McAfee Live Safe Internet Security on 30 day trial. Really want to use Windows Defender but want to know if having McAfee as a 'Vendor' application will cause problems?

Also McAfee updated recently & I find I now have two McAfee firewalls in operation.

Any suggestions?

Windows Defender Won't 'turn on'

Many thanks,

There is no McAfee in my program list, nor does an app turn up on search, nor is it present in system tray etc..

Yet...

After your last comment I looked through my services, and indeed, we have:

McAfee Core Firewall Service

McAfee Process Validation Service

McAfee Management Service

Interesting..

Now, this doesn't look like your standar McAfee AntiVirus setup, please correct me if I'm wrong.

However was this what you were referring to? Or are these services functional and safe?

I assume these were present when WD was working well last week and previous.

Many Thanks

 

I did some checking, and I think I know why. Gmail uses QUIC protocol, and not standard TLS/SSL. I don't know for sure, so if anyone could still help I would like to know. With all the hacking/issue on the web lately I'm trying to learn as much as I can.
