There's only so much we can do if the end user refuses to think. I suspect a lot of these people will be migrating to locked down/walled garden devices soon anyway.
I was watching a user a month or so afterwards to notice they just pressed enter every time an alert box popped up, immediately, without reading and without thought.
Alerts on computers aren't there to be read any more. They're confusing annoyances that you just click yes to. They're usually badly written in that they tell a normal person nothing, they're without context and usually ultimately exist because a programmer was prevaricating on making a decision.
We nagged our users too much as programmers, to turn around and blame them for not thinking is a sublime irony given that we were the ones not thinking and constantly asking for reassurance that it was us not making a mistake.
Considering that polished pieces of software ship with typos as well, it isn't an indicator of a virus or malware.
