On the system dashboard, check the License Information widget. The Support Contract section should show Valid Contract and the contract expiry date. If your FortiGate unit is not registered, you need to visit the Fortinet Support web page (http://support.fortinet.com/) to register. Go to Product Registration and follow the instructions.

In the FortiGuard Services section, check the Antivirus field. If the service is unreachable, see the online Help for information about troubleshooting your connectivity to FortiGuard Services.
