# If no update attempt has been done, an alert will be output to inform

# If you have stopped using ClamAV and would like to get rid of the
# alert, you should delete the logfile. If there's no logfile, no alerts
# will be output - but if Logwatch finds a logfile and no update attempts
# have been made for whatever timeperiod Logwatch is analyzing, an alert
