Turn off cron?

About every hour I get an email from Piwik (see below).
I have no idea what is going on, but I would like to stop it.
How do I stop this cron job - or at least the emails? It occurs on its own… I don’t recall creating it.
Any help, greatly appreciated.

Email received every hour
Subject: Cron php /home/xxxxx/public_html/stats/misc/cron/archive.php – url=http://xxxxx/stats/

Using this ‘archive.php’ script is no longer recommended.
Please use ‘/path/to/php /home/xxxxx/public_html/stats/console core:archive – url=http://xxxxx/stats/’ instead.
To get help use '/path/to/php /home/xxxxx/public_html/stats/console core:archive --help’
