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.

Any help you can suggest, or facilitate would be highly appreciated. Thank you. I'm getting tracker push notifications on my phone.
