Thanks for reporting this. According to the log, package installation seems to be stopping because clamav user already exists. Can you try uninstalling the offending packages as following:
sudo apt-get remove --purge clamav-base clamav-freshclam And install them again? However the existence from an user should not stop package intallation, so i marked this issue with low priority to be fixed.
