However Google maintains high-security standards while approving Android applications into the playstore, but some of the apps have affected with Xavier script because of their weak security features.
TrendLabs which is popularly known as internet security analyzer claimed that they detected a malicious Xavier ad library script on 800 Android apps which have been downloaded million times from the playstore. The company security analyzer also said that most of the affected Android apps are found in utility categories such as wallpaper downloads ringtone and photo manipulators.
