error when running "clamav-unofficial-sigs.sh --force"

[e-ferrari]

Hi,
when i invoke "clamav-unofficial-sigs.sh --force" i get the following:

################################################################################

But searching for a not closed " i don't find anything (hoping my regexs are correct):

root@f-mcd:/etc/clamav-unofficial-sigs# grep -v '#' /etc/clamav-unofficial-sigs/master.conf |grep -v '^$'|grep -v '".*"'|grep '"'
root@f-mcd:/etc/clamav-unofficial-sigs#

root@f-mcd:/etc/clamav-unofficial-sigs#

Any idea ?
