Starting with Kaspersky Endpoint Security 12.3 for Linux, the agent reports "Application databases loaded" instead of "Anti-virus databases loaded" and no longer emits an "Anti-virus database records" line. As a result, the AV Update Status service went UNKNOWN with KeyError: 'Anti-virus databases loaded'.

The check now accepts either of the two key names for the loaded-status line and skips the database-records line when it is not present. The service reports the available information again instead of crashing.
