Fake Avast Mobile Security download link ?

A day after remote installation of a probably fake Avast Premium Security app on my desktop, I received an email from “notification@email.avast.com” recommanding to install Avast Mobile Security on my Android device. Is this address known as a real Avast emailing address or is it a fake address, trying to induce you to download another fake/spyware on your phone ?

I would be more interested in the comment:

e.g. how did this come about and or how did you know it was fake ?

If you hovered the mouse over that link in that email, what does it show ?
