This only shows up in /var/log/syslog.

freshclam's own log file, /var/log/clamav/freshclam.log correctly only 
contains the last part, i.e. 'Downloading daily-19559.cdiff [100%]', 
just as it would appear on the terminal.

The problem is that the systemd journal does not respect the carriage 
return '\r' by deleting the current line content, but rather continues 
to append the message.
In 'journalctl -u clamav-freshclam' this output is suppressed as 
'freshclam[2421]: [1.6K blob data]', but it is still forwarded to syslog 
and there the carriage return is replaced with '#015'.

The fix for this would be for journald to correctly interpret the 
carriage return. Therefore I'm reassigning this bug to systemd.

Best regards,
Andreas
