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.

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. 😞

Hi, thanks for your feedback. If you minimize the app during a manual scan then it should continue, but will take longer. This is because scanning is slower when running in the background. As your phone is very full then this could also be a factor. Please contact us https://www.certosoftware.com/contact-us/ and we'll be happy to assist further.

Great app reasonable price plus free 7 day trial. Just during the trial,I had a real bad problem .My phone had been hacked so bad I could not even Uninstall apps was basically nightmare the battery would dump out so fast. Then I got this app,it made it so I could Uninstall the apps I did not put on there, and basically long story short had corrected all the problems in less then half and hour .now I continue to use on daily basis, and when trial runs out,I'm paying the reasonable 12.99 year subs
