Example log message:
server freshclam: connect_error: getsockopt(SO_ERROR): fd=5 error=110: Connection timed out
This is a temporary message. It means the antimalware signature update system could not connect to the update servers. This is generally just temporary and the system will retry. If you see continuous messages this can mean that there is a local network problem, such as local firewall rules or network problems are preventing the system from updating and those local network issues should be investigated further.
