It reads the TXT record for 'current.cvd.clamav.net' which has a TTL  
of 1800 seconds. Running freshclam more frequent than once every  
thirty minutes is therefor in most cases just wasting CPU cycles, as  
the previous answer will be used then. Even if the answer isn't cached  
locally, chances are it will be cached somewhere upstream.
