Thanks for reporting this bug.

This "Binääritiedosto" comes from grep, because it thinks
/etc/clamav/freshclam.conf is a binary file. Probably there is some
character in there which is invalid in finnish locale.
For the full message from grep, see e.g.:
$ grep ELF /bin/grep
Binääritiedosto /bin/grep täsmää hakuun

Using the '-a' flag of grep avoids this problem:
$ grep -a ELF /bin/grep
ELF<binary data>

Thus I changed clamav's maintainer scripts to use that flag.

Well, it's not all english:

This is very likely the culprit.
Did you perhaps use packagekit (or a frontend for it) to install clamav?
If so, have a look at bug #777481 [1].

Best regards,
