This app should not buy here because you can protect only 1 single device for the price of 9.99 euros when upgrading to the full version here at Amazon. Subtracting the same app in Google Play Store you can protect up to 5 devices simultaneously Android for the same money. So important for people who have several mobile phones or a pad, load this software here. In Google App Store, I give it 5 stars because of virus protection, performance and ease of use are really very good.
