Each event in the Alert Log includes a timestamp (date and time when the event was logged) and information about the alert type (the rest of the information varies by alert type).
The below table describes the different system alert messages that can be set in Kerio Control:

Kerio Control sends this alert when the antivirus engine fails to check files, e.g., due to password-protected or damaged data. |
