Judging the PC infections, most are entirely caused by "Clickitus"
Symptom is simply randomly clicking GUI buttons of "popups" till the "go away" without actually ever reading them.
A related malady is using the laptop/PC without reading glasses. It's thus mostly "write only" for creating documents.
Why should tinier Mobiles in less relaxed circumstances be treated better. If I was immoral I'd be writing this stuff ages ago.
