Best malware detection and removal you can find. I’ve been using this for about a year now and would recommend to anyone. I have an antivirus app as well but I always keep this app on my phone as I think it’s a deeper scan. Good additional features as well.

My partner and I both use this and it’s a great app. First time I used it it found a bunch of bad files that I think I accidentally downloaded one time and didn't know where they went. Great to know that it will find and remove anything bad from my phone. Thanks!

Really like the intruder catcher thing in this app. Used it to grab a selfie of my roommate creeping on my phone when i was in the shower. He doesn’t live here anymore after that! Stay safe everyone!

My son who works in IT suggested I try this app after I was getting lots of strange messages and things happening on my phone. Since running it once a week I have had no viruses or malware problems. I also got a VPN app so I think with both I’m all set!

So far it does as it was recommended on Google about phone hacking and known to be a trusted protection company for scans and takes like 10 mins so it must do everything..and so far no problems..also you can set it so if someone picks up your phone it takes a picture of them..really cool

Having this app definitely makes me feel more secure. I was hacked before having this on my phone, and knowing it is on my phone now takes away all the worry.

This is a great app, highly recommend. My phone was thoroughly scanned for threats, hackers etc. Thankfully there was nothing found. Also, fot some strange reason, when a ad would show a game, it would automatically download to my phone. Thankfully not anymore 🤗
