85 applications received 8 million downloads in Android

Tens of adware applications that acted as photo editing applications or as games have been caught offering ads that invaded user's phone screen as part of a revenue generation scheme through fraud.

The security firm Trend Micro said it has found many 85 individual applications downloaded 8 million times on Google Play, and all have already been removed.

Adware applications operate in the background and offer to fill telephone screens in ads to generate revenues without user knowledge.

These 85 apps other than invade advertising phones are hard to erase because they use techniques that avoid identification.

Once installed, the apps remained silent for half an hour. The app then hid his icon and created a cut on the screen. So app developers in question protected them from erasing.

The applications contained a code that allows the same ad not to appear on the screen several times. Moreover, the interval of their appearance was fully controlled by the people behind the scheme.

Tren Micro has offered a list of apps and some of them are Super Selfie Camera, Cos Camera, Pop Camera and One Stroke Line Puzzle.
