Database-Update-Question

Hi Community,

i am running a Debian machine here with Postfix / Spamassassin / Amavis and Comodo Antivirus for Linux. Everything is as it should be. Mails are scanned and
Viruses are detected perfectly. Since I am pretty new to Comodo (i alwayes used Clamav), how can I make sure, Comodo Antivir Definitions are updated regularly?
Since the Debian is a server, there is no GUI installed, just shell.

Thank you in advance!
