It looks like you have a DNS issue when this is trying to run. You
should look to see how/that dns is working on this machine. The
cronjobs run after the system startup so, in general, it shouldn't be
a timing issue but could be depending on how you have things set up.

The response that you get from a:
 
  host -t txt current.cvd.clamav.net

command should look something like:

  current.cvd.clamav.net descriptive text
"0.103.7:62:26762:1672074000:1:90:49192:333"

The *.clamav.net services run off a CDN so the IPnumbers can change
at will, so don't try to overcome your dns issue by putting something
in our resolve.conf.
