Engine Kerio Antivirus failed to start: Unable to initialize plugin, error: Failed to close Kerio Antivirus plugin. See antivirus debug log for details.

The debug logs may show such output:

Bitdefender_plugin: Failed to initialize Kerio Antivirus plugin. Status: c000001f.

Below steps can be done to resolve this:

1. Make sure the Kerio Connect server meets system hardware requirements.
2. Reset Antivirus internal folders by following Resolving Bitdefender issues guide.
