Here is /usr/local/etc/freshclam.conf:

You're running a default example of the freshclam config file that is missing all sorts of settings.

If you run:

sudo dpkg-reconfigure clamav-freshclam

it will create a new freshclam.conf file in the /etc/clamav/ folder.

Remove the existing freshclam.conf file from the /usr/local/etc/ folder.

sudo rm -f /usr/local/etc/freshclam.conf

Then create a link to the new file so that if you ever have to run it again, the conf file stays updated.

sudo ln -s /etc/clamav/freshclam.conf /usr/local/etc/freshclam.conf

Then run freshclam to update.

sudo freshclam

You might get this error: freshclam: error while loading shared libraries: libclamav.so.7: cannot open shared object file: No such file or directory, which can be fixed by running:

sudo apt-get install --reinstall libclamav6

Or for Ubuntu 16.04:

sudo apt-get install --reinstall libclamav7

Or, I haven't tried this one yet, but it has been said that it works on any distro:

sudo ldconfig

If I take this as an example I would say

LogVerbose

is NOT a valid command and it has to be followed by "yes" or "no". In the link it says:

# Use system logger (can work together with LogFile).
# Default: no
LogSyslog yes

# Specify the type of syslog messages - please refer to 'man syslog'
# for facility names.
# Default: LOG_LOCAL6
#LogFacility LOG_MAIL

# Enable verbose logging.
# Default: no
#LogVerbose yes

And the same goes for LogSysLog. That would explain your notice:

ERROR: Missing argument for option at line 33
