Type of the event upon which the alert will be sent:
• Virus detected — antivirus engine has detected a virus in a file transmitted by
HTTP, FTP, SMTP or POP3 (refer to chapter 11).
• Portscan detected — WinRoute has detected a port scanning attack (either an
attack passing through or an attack addressed to the WinRoute host).

network application (e.g. Trojan horse or a spyware) on a corresponding host.
• Low free disk space warning — this alert warns the administrator that the free

should be performed immediately.

server of Kerio Technologies during an update check. The administrator can
