User friendly, low cost, and doesn't use a lot of battery and system resources. One thing I would add for possible fufure improvement is that if the Avast can add multiple web browsers into the monitoring list (currently, it only allows for the primary browser) it may add more value to the software. Well, just a thought. Great app, and I would definitely recommend this to my friends.

There are so many options to choose from for mobile phone securities and to choose Avast has been a relief that it keeps me going knowing that it's protecting what may come. I've been sensing movements when scrolling through my mobile phone and I just had to react to certain security apps and had to stop choosing and stay with one app. So, I thank you for how you do to keep strangers from peeking into my phone. Thanks again.

Avast is suppose to be an antivirus company that specialize in defense tactics of various bugs & etc. The development team needs to get back in the lab:go back to the drawing board. I ALSO PAID FOR THE PREMIUM. When a link in a chain is found to be vulnerable you fix it. Plain & simple. App lock useless. I know it doesn't work all the time. Facts. Every so often and I mean to often app lock just doesn't work.
