What users are saying

1. There seems to be a security breach occurring which is never good for business.This service and the features in the app work well but every time I go into the app to turn on accessibility it works for a few minutes drawing over the apps like it's supposed to do but then it just shuts off and then it doesn't have the real-time protection anymore.

2. Trying to go through the verification process and it keeps trying to send the link to an unfamiliar phone number before displaying an error message and freezing on me.

3. Looking in the app settings there is a notification alert for connecting to bad wifi (which I'd want) but not for "scanned that app, all good", or indeed any app scan settings.

4. Cancelled premiumRecent update has it sending notifications everytime it scans an app update.

5. Since Google play usually does these overnight, and these days apps update very frequently, it's annoying to say the least.

6. This means that I have to go into the app almost every single day turning the real-time protection on! Also the app locker does not work.

7. Where did the memory booster go? Worked well enough, now wasting time experimenting with other apps for that purpose.

8. It keeps sending me pop up notifications about it keeping me safe 24/7, & I have notifications turned off.

9. Needless to say, this will wake you up in the middle of the night.Was not expecting a radical change with the last update.

10. Security is important to be sure but shouldn't be this complicated for anyone who isn't a tech expert.Suspicious activity.

11. Tech support told me to click Fix and I would get an option to ignore the file.
