Ratings and reviews

I don't give 1 star reviews easily. I have no honest choice but to give this nothing higher than 1. I subscribed to the 7 day free trial and attempted many times to scan my phone. It will only scan when the app is open and the screen is on. It will stop any time other than that. I couldn't ever get a scan to complete on my admittedly crowded phone memory. I cannot say this app accomplishes anything but to look like it's scanning, and it doesn't even do that as it should. I'm sad to say it. 😞

I feel like I must be doing something wrong. I KNOW I've been hacked. Malware on my network and/or devices. This app is highly recommended and I had high hopes, even though it's like the 30th one I've tried over the yrs. Any ADVICE??? I'll have my whole family give 5* Steller reviews if you can help. So tired of having to wipe or swap& all that constantly. If I had any more security, Id have no signal. I'm lost. The hacker has won. I give up. They know cuz they can see this in real time.

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 🤗
