The app simply doesn't work. I get to the subscription screen and then it just freezes. I've restarted the phone, cleared app data, nothing. It might be a great app but I will never know. Get it together Microsoft. Your free apps work all off the time just as intended and you can't get a paid app to work even once? Extremely disappointed.

When you have to turn off your antivirus to perform basic functions you end up leaving it turned off. If you turn it on completely, most of your stuff will not work. Your watch can't keep track of your vital signs. You can't log into any of your trusted sites. Pandora won't even log in or work properly. My healthcare app will not log in or show me any of my info, even while at my doctor's office. and there's no way to adjust or allow anything. But you'll keep getting notifications.

The experience has gotten much better. I repeat do not install Avast . Ok this app does now show it's scanning and it shows what it has scanned if it's a threat. The app is good for this it also features a private browsing session that word really well but on some sites I had to turn not off. So I went with a VPN that I purchased . That app is very professional and so far I love it. If you want a good combination of security I recommend Microsoft Defender and Nord VPN. They work well together.
