That’s why I am saying it’s unnecessary. The > restrictions are on the files themselves. So you're saying that if -- because I wanted to get an update ASAP in the face of a severe virus alert -- I upped the running of freshclam to every 5 minutes on each of my 3 systems, there is no chance that I would be blocked, because freshclam doesn't do any actual (restricted) file access until after it checks the DNS TXT record? Even if that's the case, I think it would generate a lot more junk in the log files than my current approach does (since I run freshclam with the "-v" option). _______________________________________________ clamav-users mailing list [email protected] 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
