Norton Safe Web scanning frequency?

Our site www.sexy-panama.com has already been scanned and received an OK/GREEN rating. 

 

However, I'm wondering if the site will continue to be scanned periodically in the future?  I'm assuming that this is the case, but I did not see any information confirming this.  Could someone confirm that the site will be scanned periodically (maybe daily, weekly, etc) by Norton in the future?  Thanks!
