Consider this a lesson in taking app claims (and user reviews!) at face value. Uploaded on March 28th, Virus Shield was the third most popular paid app, and the most popular overall, on the Google Play Store. Retailing for $3.99, the app promised to search a user’s Android smartphone for viruses without affecting battery life. In a little over a week, it had been downloaded more than 30,000 times and had received multiple 5-star reviews.
Unfortunately, the app didn’t do anything. Well, when pressed, the app’s icon changed, but as Android Police concluded when it examined the app, there was no additional code within to do anything else.
