Sonar Deleting Part of Audible Manager Program

I use and puchase Audiobooks from Audible (a wellknown company) to download these Audiobooks I use a program provided by Audible called"Audible Download Manager.

Part of this program is a file called Audiblehelper.exe, just recently, Just as I start downloading my purchase or sometimes halfway through downloading Sonar deletes this file and calls it a Threat. This is a Reputable company with good clean programs. I need a solution or I will not use Sonar.

 

Can Anyone help
