Solution

Sophos is considered as a legacy Antivirus provider, prior to the 9.2.1 version, that's why no updates are provided to the older versions of Kerio Connect and its virus databases. Sophos was replaced by the Bitdefender Antivirus engine.

If you have Kerio Connect 8.x, such as 8.5.0 or older, please use the following procedure:

Note: if you're running Kerio Connect 9.0.0 and up, steps 1-3 can be skipped.

Uninstall the current Kerio Connect version.
Depending on your OS, download Kerio Connect 9.0.0 from Kerio Software Archive.
Install Kerio Connect 9.0.0. For more information about the installation, please refer to:
1. Install on Windows
2. Install on Linux (Deb, Rpm)
3. Install on Mac
Perform an automatic upgrade from the Webadmin -> Configuration -> Advanced Options -> Software Update.
Wait for the Bitdefender Antivirus definitions to be updated.
