I have used this app for a few months now with no issues. It runs in the background, scans in real-time, and doesn't slow anything down. I'm still able to use every app I have on my phone with no issues whatsoever. To be honest, I forgot it was on my phone until tonight when it needed an update. (I do manual app updates). Microsoft scans your phone, computer (PC app required), the dark web for your info and so much more. VPN works great for using public WIFI and 5GB is included, all for free!!

Originally worked, but slowed 300 mb to 5 mb. Turned privacy off, worked. Went on a cruise ship (starlink, probably). Could connect, but was getting absolutely no data up or down - while others were fine. Privacy was back on (not by me). Worked fine. Later, same problem with privacy off. Uninstall is the only thing that fixed the problem. One star, though many features would be great to have, because it's totally useless if it blocks all traffic of any sort.

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.
