Ratings and reviews

This is the absolute best portable smart phone and portable smart tablet security app. It knows how to close apps taking temporary memory and it can instantly fix all kinds of malware and riskware. I like this one better than Lookout because it does not mind an app that has a screen overlay whereas Lookout once messaged me that I had a screen overlay interfering with its operation. I want screen overlays for some apps that I like and for apps that require it.

I've had a virus on my phone for a year now and not one virus scanning app could ever detect it but this one did. It was a major vulnerability with the OS which caused my pre-installed apps to be uninstalled and replaced with bogus ones. Not only that but who ever downloaded this into my devices also had remote control access and was spying on me. Thank you SO MUCH Netqin!!

I've been using NQ for several years with no problems and loved it. Lately, erroneous Network Connection issues ongoing. I haven't been able to update virus scan. I've lost confidence in the product. On top of that, I just re-upped my re-subscription but it looks like my refund won't take effect until the END of my subscription in 2020. Question remains: Does NQ still have access to my phone??
