Aside from avoiding any downloading of apps on an unverified site, perhaps its high time to invest a little more on our systems / mobile device's security (e.g. subscribing to popular security apps) that would minimize our chances of being pawned.
If we can't do it, at least we should regularly update any antivirus apps that we have to keep our defences more active.
I have always had an attitude towards my mobile device in the same way as to my computer, which means that I have always taken care that it has the latest update and that it has some solid AV, with of course great caution for every app I install from Play Store. The problem is that many of today's mobile devices are out of date (too old to get updates) and apps like AV slow them down because of the very low RAM and weak CPU - and that's exactly what hackers are counting on.
What pisses me off on some of those researches about viruses and malware is they forget to add one critical fact, how it happens
If you get a message on any social network or via SMS/e-mail from a pretty girl who sends you her pictures or video I would bet it's malware. Of course, hackers are very resourceful in achieving their goal, and what children need to be taught in kindergarten is that the Internet is a very dangerous place and that everything should be approached with a great deal of caution. Some would say that it may be too early for children to deal with such things, but iron is forged while it is hot - of course if we want a future with fewer who will be victims of such things.
