I have the same problem - every so often (30 - 60 minutes) the service stops, and bizarrely the shortcut appears on my desktop (I delete the shortcut since I can access the application from the task bar).
I have just installed the latest version (11.1.2245) and the services stopped.
I have been using Avast forever and apart from the odd false positive, this is the first time it has played up.
