There used to be limits on the number of time you could run freshclam, as memory serves it was four times an hour unless you did something specific (which I’ve forgotten) allowing it to be run more often, but lots has changed since then. The most important thing for you to understand is that the ClamAV signature database is almost never updated more than once a day, around 9am GMT, plus or minus a half hour. And since running freshclam when there isn’t any new update only checks your local DNS there is no impact on any CDN so it’s strictly up to you on how often you want to waste computer and Internet time to run that DNS check and how critical you feel it necessary to have an update as soon as possible after it’s posted. I see mine is set at four times a day, though I don’t recall how I came up with that number and can’t really recommend what cadence needs to mean in your case. -Al- — CalmXAV User
