Avast HIPS blocking Viber

Hi there, does anyone know how to stop Avast HIPS from blocking Viber (free messaging service)? I have the HIPS settings on high/3 bars and it asks me everytime I start my PC to allow or deny one of Viber’s files to run. I have tried to add the application’s directory to the exclusion zone in both the General settings and File System Sheild settings with no luck.

Here are screenshot attachments:

Delete the item that is on the exclusion zone and see what happens when you set HIPS on low/1 bar?
