When "unmatching security certificate" is issued, how can I verify that the website is safe ?

Dandall

I have contacted the site and of course they say it's nothing to worry about and that their website is secure. How can I verify that?

As said in the article, you can check the website's certificate here:

I think it's ok to add the site to the exception list in this case.

Done.

Thanks for the reassurance!

Excellent articles and support links! Thank you very much!

I do have an additional question about removing adware:

How do I determine which app has embedded adware? I have 89 apps. Many of these I have no clue as to what they are for. I don't want to remove anything that I may later regret.

Thanks so much for your support!

Thank you for the additional procedures.

As I am learning more about this and reread the results from the SSL checker, I think in this case the warning is not that big of an issue. 

Please correct me if my understanding of the results from SSL checker are not correct.

It resolved the site address to an IP address and gave a green check.

So, I'm assuming that the certificate for this IP address is valid.

It identified the server type as msys-http with a green check.

So, I'm assuming this is also acceptable.

It states that the certificate should be trusted by all major web browsers and that all correct intermediate certificates are installed with another green check.

And the certificate is valid for another 300 days green check.

The yellow warning states: None of the common names in the certificate match the name that was entered (tracking.centene.com). You may receive an error when accessing this site in a web browser.

I'm interpreting all of this as more of a "clerical" issue just because of a "common" naming issue and not with the security associated with the IP address. And therefore, I should be safe with adding this site to the exception list in Bit Defender?
