Sonar

Hi can anyone help I run Norton 360 on my laptop which I use for my business. I recently up dated my subscription of 360 up till then I had no problems at all. I had a programe installed  which was worked fine the programe is used to edit a digital moving sign to read anything you wish to put into it . As I said all was fine until the update now Sonar thinks the editor side of the programe is a threat and deletes it, I can use the programs but I have to turn Sonar off leaving my computer open to  attack. as soon as i turn it back on it revoes this part of the frograme. Is there a way of making sonar recognize this software so that it is no treat as I have used it in the past.
