and people say Android malware isn't an issue? I saw a chart somewhere, that showed the growth of android malware is something like 900% a year.. I will find the chart.
Yes, most of the malware comes from installing malicious apps. There are not much exploits or malware using Android vulnerabilities floating around, though.
I agree that Android malware growth is indeed a worrying trend and concern. However, I don't share the same sentiment that a real-time AV is necessary provided certain precautions are taken. If we look at the malware distribution channel, we can see a pattern where the majority of the malicious apps come from unknown sources (such as dubious 3rd-party stores) and malware that infects Android devices via USB connection. By leaving the built-in security settings at default and not installing apps from these unknown sources, the exposure to such malicious apps reduces by a huge margin. I am not denying that there are malicious apps on Google Play Store but Google is taking steps to reduce the odds of encountering one. Furthermore, it's not difficult to create a wall for oneself by sticking to known trustworthy reputable apps.
