Android and Malware: Using an open platform, like Android means you should be willing to risk the bad along with the good. Without wanting to get into a pros and cons between Android and iOS debate, it is a fact that Android hosts more malware than the iOS platform and this is due, in part, 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 is behaving suspiciously or doing things it's not allowed to do with settings or security protocols (without permission).
If an app tries to interrupt communication between Google's servers and the device, engineers analyze the data connectionand find out what the app 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 applications with Malware from the Play Store.
