Avast have created a list of dangerous Apps on the Google Play Store that you should remove from your Device immediately.
According to Avast:
When a user installs one of the apps, the app checks their location, International Mobile Equipment Identity (IMEI), and phone number to determine which country area code and language to use for the scam. Once the user opens the app, a screen, localized in the language their device is set to, prompts them to enter their phone number, and in some cases, email address to gain access to the app’s advertised purpose.
