I use Ispconfig Version 2.1.2 and work exelent, but i need to update only the antivirus engine because the clamAv is out off day. Can i do this. How
freshclam should run from a specific cronjob (set up by ISPConfig's installation). It is not meant to update your ClamAV installation by hand normally. Do you have any errors in /var/log/maillog?
