Everyone generally expects to download an application from an official store such as Google Play, it is secure and contains no malware.
However, experts warn that some applications are only "wrappers" and offer no real functionality, but rather scan the user's phone with ads.
Trend Micro warned that millions of people were downloading applications claiming to offer a multitude of features, but that they only functioned as channels to show annoying ads to those who installed them on their computers.
The company has found about 85 applications, which have been downloaded in total about 9 million times, all working in the same way and using similar code.
One of these apps claims to be a "universal TV remote", while another focuses on car games. After downloading one of these apps and others, users will see a full screen ad, and then continue to see the ads in each of them. Press any button.
In many cases, the application seems to disappear from the phone and does not appear on the main screen, but it continues to run ads.
These ads appear every 15 to 30 minutes and are expected to generate revenue for developers and frustrate users. As always, these applications can have a significant impact on the phone's battery life, as they continue to operate in the background and can prevent it from "sleeping". .
Although many of these apps have been removed from the Google Play store, a number of them still exist in the online store for Android users.
The best way to prevent your phone from being hacked by ads is to install a malware scanner. Trend Micro has one of these applications, which you can download for free on Android and Ios.
