I don't understand why people hate this anti-virus so much. It is really good and supported by Microsoft. It gets the job done. Has a few interesting features. UI is very intuitive and not overloaded by tons of widgets like in other anti-viruses. I haven't noticed any problems with battery life or performance. It shows protection status for other devices that you connect. Totally recommend. Really good for a free anti-virus

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.
