In short, yes. You can run multiple ClamAV daemons. Simply launch each daemon with a different config file for each daemon and then you can have clamdscan processes talking to each of those daemons. At a minimum, you would want to use different sockets for the daemons to listen on. You could set up each daemon to use smaller virus database sets, but that really only impacts the speed at which the daemon reloads when there are database changes. Are you trying to reduce the time that it takes to scan your entire system? Or is there some other reason that you are looking to run multiple daemons? “Increasing CPU usage” isn’t generally one of the things people look to do just because it’s low. > I am aware of the multiscan mode in clamdscan but I want each scan to be a > separate process so as to not increase the overall scan time of any one file. > Is there a way to do this?

You can run multiple clamdscan processes against a single clamd daemon and it will just spawn more threads to do the scanning. So, for example, you can have a separate clamdscan process working each user’s home directory in parallel and they should all be able to talk to a single clamd daemon. —Maarten _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
