Yivi--In regard to Android being immune from viruses, well, to quote a dead late-night talk show host: "I did not know that!" I have to read the PDF Ivanjt suggests, because I don't know how to grant permissions or if you can pick-and-choose which permissions you'll grant...while still being able to use a particular app. I am learning so much just being Nag of the Month here


but will stop at the stroke of midnight January 31.
Ivanjt--Thank you for the search tip. You're right about misconstruing the verb "hack." Similarly, I didn't know that the apps not being the latest (for our Edges) and our devices not being phones would tend to offer protection. Nevertheless, I am sticking with geography quizzes on Ilike2learn until I read the information you suggested. Just having an Edge is so cool that I don't care how long it takes me to learn Android.
