Hi, does anybody know, why I am not able to start the AVG antivirus on Mac so I could have the real-time protection and scan my computer as well? It always gives me an error unable to initialize antivirus controller. I have already tried to reinstall however without any success. I am using Macbook Air with OS X 10.11.1

Thx for advice
