This is the worst app since it has been updated. You have too put in your password multiple times to log in. When trying to make a purchase you get an error message and after multiple attempts I had to put in all my information in again. Its unstable, it will go to another web page without the screen being touched. This app is a hot mess.

For some reason I started getting pop-up ads for dfndr. They popped up at random times. In the middle of texts, emails, everything. So I installed the app and ran the checks and fixes. Still getting the pop-up ads. Most redirect to this app on the play store. Absolute RUBBISH!!!! You give us pop-up ads that direct us to your product, then the product does nothing about the ads that IT caused. I guess it's a way to get people to pay for service... Ya know, like ransomware.

Wow! So many 1 ⭐ reviews. I've been using this app for about 3 years and I only get pop ups if I haven't actually read through the options on the homepage and forgot to stop receiving the pop up. Usually after an update you have to update the notifications that you want and select the ones you don't. After switching providers the cleaner that I had been using forever wasn't available. So I did my research and chose this one. If it's not for you be sure to delete before trying new apps.
