Attaching the log file which seems to relate to clamaav as it was not automatically attached. This file was taken from /var/log/clamav/freshclam.log and seems to show the error extending back to the beginning of the month.
If I look in the oldest rotated copy of the long on my machine I can see evidence of the problem extending back to at least the end of July without my noticing until now.
