Android and Malware: Using an open platform such as Android means you should be willing to join with the good to risk the bad. Without going into a conversation with the pros and cons between Android and iOS, it's true that Android hosts more malware than the iOS platform, and this is partly due to its open ecosystem.
Google's engineers are constantly trying to find ways to detect malware coming up in the Google Play Store and waiting for unsuspecting users. 
A recent Digital Trends article describes how this is done, according to Google.
According to Google, therefore, each application has been scanned for malware and other exploits before it reaches the Play Store.
But we've noticed that scans are not always helpful, and any app you download might contain some malware or other unknown exploits.
To combat this, Google is testing every app through an Android device. In other words, it installs normally from the Play Store in a normal device environment. It then waits by collecting the information that is transmitted between the device and the Google servers.
So engineers can see if the app behaves suspiciously or does things that can not do with security settings or protocols (without permission).
If an application tries to interrupt communication between Google servers and the device, engineers analyze the login details and find out what the application installed.
Let's say this is one of the many ways Google uses to protect Android users.
But we should add that none of these processes are perfect and you can still download Malware apps from the Play Store.
