Uncovered by Android Police earlier this month, the fake virus scanner was nothing more than an icon that changed shape when a user tapped it.
Now, Android Police has learned that Google is issuing refunds to purchasers, and giving them a $US5 Google Play Store credit.
According to Appbrain, downloads hit 30,000. At that scale, Google would only have to fork out $US120,000 in refunds.
The developer of the app, Jesse Carter, defended himself to The Guardian by saying the app upload was a mistake. At the time, he'd promised to refund buyers, but El Reg notes that Google seems to have decided not to wait for Carter to issue refunds
