I am using clamav to filter mail but can't figure out how to set the nicelevel. There seem to be two applicable files: /etc/default/clamav-daemon /etc/clamav/clamd.conf The clamd.conf man page mentions "nice" not at all. I've tried: NICE="--nicelevel 10" in the clamav-daemon file but it made no difference. Perhaps someone can give me a push in the right direction; thanks.
