The site's security certificate has expired! You attempted to reach login.yahoo.com, but the server presented an expired certificate. No information is available to indicate whether that certificate has been compromised since its expiration. This means Google Chrome canno开发者_开发问答t guarantee that you are communicating with login.yahoo.com and not an attacker. You should not proceed.

An SSL certificate has an expiry time. login.yahoo.com expires January, 4th next year (2011).

Your browser compares this date with your local system's date. So check, if your system clock isn't wrong.
