Much has been said about the Google Play Store in recent weeks, but not in a positive way, but it is a negative impact on its image and reputation among users, due to applications, because it was found that most of them only harm those who download, In newly discovered cases.
Trend Micro, a company that analyzes security threats in software, has found that 85 applications infected 9 million users with adware.
 Ads are spam or unwanted advertising that is commonplace for businesses to be present all the time on mobile phones to users even though they do not want to.

Although these applications do not expose the user or his phone to danger, it is tired when you pretend that these applications are a simple game or a remote control application or a television application and when opened, you only find large amounts of ads.
This is very annoying, as it turns out that once installed it hits the phone and the ad appears every 15 or 30 minutes or applications are running in the background even though they are not opened manually.
For this reason, and after reporting to Google, the Google Play store has removed these applications and it has been recommended that if you see such kind of problems or strange behavior, you immediately dispose of the application.
