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.

I have used this app on the phone without issue for a few months now. And I have used them for years on my desktop. I haven't ever run into any issues while using Avast. But my favorite part of Avast us the vast amount of features and very precise settings. You can fine tune it exactly how you want it to work. Top quality anti-virus in my opinion.

I kept getting forced ads I couldn't exit on my home screen. No apps running but they would constantly pop up. So I thought "malware?". I tried a few different apps and they said my device was clean but it kept happening. Eventually I tried Avast. It immediately found the malicious software and removed it, no problems since
