I am not surprised at all that Lookout caught this and exposed it, I was part of the initial development team when it was still called Flexilis and we started the project originally intended for the Windows based phones to protect them against OS specific malware, but then expanded and applied that to the other platforms as well, specially that Android became very popular.
Clearly, if you are running inside a browser, use NS and you are safe, but even outside of that, download and have Lookout running on your phone/tablet because it is the first of its kind to handle malware, viruses, quasi-firewall (the reason I say quasi is because it requires root for low level protection and many phones under contract are locked = no root access), and also protects your device by locating, locking, wiping and aiding in its recovery and that's all in the free version, the premium version gives you even more.
Its a must and all the knock offs by Avast, Trend Micro, Norton, Comodo, AVG and Webroot to name a few are just late comers to the party who are mimicking it and realizing what we realized a long time ago and that is mobile devices need as much protection (if not more in the world of people using mobile for everything) as the regular machines, but the difference is we built it from the ground up when there was no such thing out there, they are just piggy backing on their name recognition with nothing more to offer in way of better quality.
Good luck and take care. BTW, Tom, leave the bias to me

you are too modest.
