Malwarebytes isn't to bad of software because of its large database for malware signatures. If you are thinking about putting it on mobile I can't honestly say I have tried it, but I'm pretty sure it works just fine. As far as the other two I was talking about Appbrain is simply just something that scans through your apps and finds what the apps have access to and it also alerts you if anything has changed when you update an app, so think of it more like a monitoring program for your applications. It doesn't offer protection, it is more for monitoring purposes. As for the lookout I actually discovered it by accident when I bought I new LG G3 a year ago before my current it came with it and it worked amazing both free and pro.

But I've done my own benchmarking with my own pieces of code that I either wrote or rewrote and recompiled and they all work similar no matter what really the benchmark tests show for the different AV's. Like if you wanted to get really good protection the best I have found is F-Secure for mobile which if you pay a bundle fee you get both their AV and VPN service. I really think you will be happy with any that I listed as I mentioned earlier. Just stay basic and up to date when it comes to mobile security. Don't install to many apps, check permissions for games, and always avoid apps that aren't in Google play even though some of the apps that make it on the market are also malicious. That is about all that I can recommend for a regular user. If you want to know anything else like how to make end to end encrypted calls and text as well as web browsing you can always just PM me your question.
