What does WARNING: DNS record is older than 3 hours mean?
• freshclam attempts to detect potential problems with DNS caches and switches to the old mode if something looks suspicious. If this message appears seldomly, you can safely ignore it. If you get the error everytime you run freshclam, check your system clock. If it is set correctly, check your dns settings. If those didn’t help, try putting this at the top of your cronjob: host -t txt current.cvd.clamav.net; perl -e ‘printf “%d\n”, time;’ The 4th field of the first line should be less than 3 ∗ 3600 behind the output of the second line. If not, you have a caching DNS server somewhere misbehaving.
