An excellent Tutorial and a nice recommendation of avast! Free Mobile Security.
Necessary? Its not a guide or tutorial at all, its just a picture.
A tutorial explains steps, has a purpose and tells you what to do (sort of)
The link to the tutorial (and I would call it a tutorial) is above the image posted in Bob’s post, though it isn’t about AMS as such but how to Set up avast! Anti-Theft on an Android phone.’
The recommendation for AMS is at the top of the page.
