I managed to fix the problem by opening the Synaptic Package Manager, then selecting all installed ClamAV and ClamTK packages, for complete deletion, including configuration files and installation logs, in addition to all the suggested packages.
Once that was done, I did a fresh installation of ClamTK and all the recommended and suggested packages.
Then I had to recreate the file 'clamd.conf' in etc / clamav, and finally, everything worked again normally.

Thanks Iron-man for continuing on this issue and fixing it via resetting your daemon config.

From the log:
/var/lib/dpkg/info/clamav-freshclam.config: 137: export: http://database.clamav.net: bad variable name

I haven't seen this issue anywhere else yet, if it was a custom config fine.
So for now this bug is incomplete (in the sense that we can't fix anything in the package itself to avoid it).

But if you think you have spotted a bug e.g. a general path of actions that leads users into the case you have hit - then let us know and set it back to new please.
