Yahoo mail connection not safe. How can I restore it?

[dimdoc]

When I open my yahoo mail, on the top left side of my browser, there is a padlock that is normally green in color indicating the site is secure. Now I see a yellow triangle (with an exclamation mark inside it) superimposed on the right bottom side of the padlock. When I place my cursor on it, it says:

"The website does not supply identity information"

When I click on the padlock, I get a drop down message with the following:

"us-mg6.mail.yahoo.com
Connection is Not Secure."

Then follows the yellow triangle again with the enclosed exclamation mark, and the following message beside it:

"Parts of the page are not secured (such as images)."

I have read though the Information section and have understood the explanation of all the symbols, yet I couldn't find a place where it explains how one can re-activate a lost site security.

Can anybody help me with problem? Also is there a way to upload a screenshot of the problem on this thread?

Thank you.
Adimchi.

Make sure that your computer's time, including the time zone, is set correctly. Incorrect system time can cause these sorts of authentication errors.

If that doesn't resolve your issue, you should perform a full anti-virus and anti-malware scan.
