why? linux users rarely need antivirus.

Why? automatic update should work as good as manual. Unless

this is a mistake. freshclam process has to run under user "clamav" - you
may have apparently created files which later instances of freshclam won't
be able to remove/update.

go to /var/lib/clamav, chown all files to clamav:clamav and let freshclam daemon
do its work.

slow internet connection probably?
the default on debian is

ReceiveTimeout 30

it's in seconds; you can increase it if really needed.
