The Durak Card Game app, developed by the "company" Pocket Games Ltd, has been downloaded from Google Play Store around 10 million times, according to Google. After many complaints from users, security analyst Filip Chytry, Avast, began looking for the application and discovered that it has been developed in such a way as to serve strange advertisementsadware) in places unusual. 
The software waits for 30 days before the launch of aggressive spam with ads, the researcher says. This makes it impossible to link the application installation to that behavior.
“Every time you unlock your device, a advertising will be presented to you. It will warn you of a problem, e.g. that your device is infected, for some site for adult meetings or even porn. This, of course, is a lie," Chytry reports a post on the Avast blog.
“Then he'll ask you to do something. But if you agree, it will direct you to fake pages, which contain apps that try to send SMS messages behind your back, or apps that collect your data your. "
Of course particularly worrying is that the application is useswidely known. In less than three months, it has been downloaded 10 million times. Avast claims that there are other apps, such as an IQ tester, that also serve ads.
Google has already removed the malicious app from the Play Store.
