It's a decent app and has a lot of good features. However if you decide not to turn on its web security monitoring feature that has permission to monitor your screen it will constantly send you notifications telling you to turn it and that you are not protected. I had to go out of my way to disable notifications to get it to stop nagging me to turn on an optional security feature.

Four years later, still impossible to use the app on Oppo Find X9 Ultra. Moving around in circles, settings cannot be completed.

I have it on my phone and yet I'm being told protections will be removed in 18 days but my subscriptions for a year. I would give Windows even less of a review if I could but the fact of the matter is it doesn't seem to matter what they make they just cannot produce a good product. I may have to switch over to Ubuntu or Linux permanently
