Error message: This website’s security certificate has been revoked.
What it means: Do not trust this website. This error message often indicates that the security certificate was obtained or used fraudulently by the website. The encryption key that is specified in the certificate might have been compromised or the user listed in a certificate does not have authority to use it (for example, the company was sold). The certification authority that issued the certificate keeps a list of revoked certificates and that list is checked by Internet Explorer.
