The next line might be something like this: /usr/local/bin/freshclam --quiet -l /var/log/clamav/freshclam.log That will run fresh clam without any output to the console, and it will log the transaction as indicated. The other assumption is that you will not start freshclam in daemon mode. dp _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html
