Usually when I login, am on certain part of a website, or when buying things, the https symbol is shown as a green lock but very recently when ever I go to login, buy things, or am on certain parts of websites that usually have the green lock, they no longer have a green lock but have this symbol (as shown below).

This also happens when I login to websites that are usually secured by HTTPS and show the green lock.
I have even tried to download extensions for google chrome, such as "HTTPS Everywhere" and "KB SSL Enforcer". They worked at first on some websites and fixed the problem temporarily but then the symbol with the orange triangle lock continued to show up again. I ended up deleting those extensions. I have also tried to reinstall windows and the problem had mostly gone away for a short while but then again resurfaced. Can someone explain to me what's happening and how I can fix it.
