Google Chrome may show this warning if phishing and malware protection is enabled. It indicates that the URL listed in the website's certificate doesn't match the actual URL of the site.
When you connect to a website that uses SSL to transmit data, the server which hosts that website presents Google Chrome and other browsers with a certificate to verify its identity. This certificate contains information such as the address of the website, which is confirmed by a recognized third party organization. By checking that the address in the certificate matches the address of the website, it's possible to verify that you're communicating with the website named on the certificate, and not someone pretending to be that website.

If you're absolutely sure that the site you're visiting is secure, you can choose to continue to the site by clicking Proceed anyway. In general, it's best to take precaution and click Back to safety, which returns you to the last page you visited.
