Problem with NIS for Mac ( application blocking) and Adobe Reader

Hi, I don't seem to be able to stop the application blocking of the app shown in the screenshot no matter how many times I select allow.  The blocking dialog box keeps appearing (see screenshot).  My system information is as shown below.

MacOS 10.9.5

Norton Internet Security 5 for Mac (Version 5.6 (47) )

Adobe Reader XI (11.0.09)

 

Any thoughts on how to deal with this?
