This is due to the fact that an upgrade to version 4.6 or greater forces the deactivation of Kaspersky. It must be reenabled before it can be used again.

Procedure

In order to reenable Kaspersky, please follow the steps below:

• Connect to the appliance via SSH
• Delete the token KavRemoved

  setconf -d /usr/Firewall/System/global Misc KavRemoved

• Re-apply the update of the running firmware version
