Greetings: I had some security concerns since I am new to the Smartphone users. After bouncing around the Internet, reading more and more post of Apps, and security suites I became more confused. So I called Verizon. To my surprise Security is built in, Secure shopping, credit card use, and testing apparently is incorporated within their firewall and sim protection. Interesting, and I almost went for the AVG pro. Hope this helps others.
