If you want to make sure that your freshclam is updating at regular intervals, run the following command from a terminal window:

sudo dpkg-reconfigure clamav-freshclam

Step through the pages, and on the number of updates per Day, it should be set to 24 which means once per hour. Also, these setup pages allow you to set the freshclam update to a daemon so that you don't have to worry about manual updates.
