In the meantime I found my patch ws not correct. Here is the right sequence
sed -i 's/^si_url="clamav.securiteinfo.com"/si_url="www.securiteinfo.com"/' /usr/sbin/clamav-unofficial-sigs sed -i 's/^mbl_url="www.malwarepatrol.net"/mbl_url="lists.malwarepatrol.net"/' /usr/sbin/clamav-unofficial-sigs sed -i 's/if clamscan/if \/usr\/bin\/clamscan/' /usr/sbin/clamav-unofficial-sigs sed -i 's/clamscan --infected/\/usr\/bin\/clamscan --infected/' /usr/sbin/clamav-unofficial-sigs sed -i 's/clamscan --quiet/\/usr\/bin\/clamscan --quiet/' /usr/sbin/clamav-unofficial-sigs sed -i 's/\/usr\/bin\/\//\//' /usr/sbin/clamav-unofficial-sigs I hope that my patch will be included in bullseye
