Receive a certificate error in Internet Exp 11

  1. Mar 21, 2015 #1
    I use Internet Explorer to get into my sbcglobal.net email. It has been working fine all these years. All of a sudden, my desktop gives me Certificate error when I click the "Mail" in Yahoo page. The message is:

    Security certificate presented by the website has expired or not yet valid.

    Security certificate problem may indicate an attempt to fool you or intercept data sent to the server.

    My other computers work fine on the same network. What is the possible problem? Please help.

    Those are valid security messages. Maybe your other computers have relaxed internet security.

    But even yesterday, the desktop worked fine. Just all of a sudden this morning I got this message. What can I do to fix it?

    Consider that the security certificate has failed in the interim. A useful browser's error will give some options and reasons for the certificate failure. As a matter of fact, I just tried to visit sbcglobal.net to see that its IP has been hijacked.

    More than likely, your other computers have the message turned off in their IE settings. You can make the message not appear in IE but then you won't have any warning when a web site is using a fake certificate. However, "Fixing it" isn't what you should do. You should be more concerned that your other computers aren't warning you.

    If I read Doug Huffman's last post correctly, your browser is warning you (like it should) that the site has been hijacked. Hijacked sites usually have viruses so if you want to install yet another virus on your computer, turn off the warning and have a nice visit to 'sbcglobal.net'.
