The level of a site's security is shown in the SmartBox using the following icons:
The icon shows that the site uses a secure protocol for transmitting your data (HTTPS), and that the site has a current SSL Extended Validation (EV) certificate. Make sure the page header shows this icon before you begin entering confidential information on a website (for example, your bank card number).
The icon shows that the site uses a secure protocol for transmitting your data (HTTPS), but the site's certificate is less secure than EV.
The icon indicates that either the browser could not verify the certificate's validity, or the page contains dangerous elements.
The icon appears if this site may be harmful for your computer.
