Environment: MacBook with macOS 10.12.1
I am trying to install Avast Mac Security, but I always get an error (see screenshot). All StartUpItems, LaunchAgents and LaunchDaemons in /Library, /System/Library and (User)/Library are clean. So there should not be anything left which causes problems.
What are the reasons for showing up this error?
Thank you for your support!
