"Skype is safe" notification

An Avast notification appears on my home screen saying “Skype is safe. Tap to open.” When I tap it takes me to the Avast screen (“Shields are on”). How can I turn of this notification? It’s been on since yesterday.

Hi Tom, what version of AMS do you have?

Version 4.0.8139

Now I’m getting other notifications that I can’t seem to do anything about. “Set Password for Google+” (I’ve disabled that app, but still get the message), and “Avast is protecting you”
