you can try to delete all files in lib folder and start freshclam again.
by the way: you should maximum once per day refresh your signature files otherwise the cdn will block you for 24 hours.

Betreff / Subject: [clamav-users] freshclam: Verification: Can't verify database integrity
> What the heck could be causing freshclam verification problems for the
> past 2 days?  I'm getting rate-limited over and over because freshclam
> fails to verify daily.cvd (and then retries over and over).  Is there a
> known problem with daily.cvd downloads being corrupt?  Google says to
> "wget http://database.clamav.net/daily.cvd" but that no longer works.
> What should I be doing differently?
