    Whenever I am on reputable websites that I always use, this security thing pops up (attached photo). It most recently happened on yahoo. Just wondering what this is, and if I should be concerned?

    It happens when the webmaster forgets to update his security certificate or said certificate expires.

    If you are browsing a known safe site (such as Yahoo), then you shouldn't worry.

    On more shady websites, I'd be leary.
