It's a constant marketing ploy to sell you other "clean-up" applications, and is invasive so that when you would like to access your phone, you get these additional messages that are difficult to get past, usually involving a restart. Over the period of my career in supply chain management, I and my staff, have spent billions of dollars for goods and services. This ranks towards the bottom, I would like a clean system process, and a full refund of the money I paid and damages for this.

AWFUL! Recvd ominous warning about viruses on my phone. Installed cleaner app for free then received notifications for 10 other apps. I don't want to pay for monthly service. Have been receiving10+ app notices per hour ever since. Notices will not stop even when un-installed. This is a harassing sales tactic and needs to STOP!!!!!

This is an excellent app. This app has beleted file virus and I haven't thought the cleaner toll was fit for removing virus. Now I wanna see what it do against spam call. I'm impressed with cleaner too. app.
