xxx 1.3.9.apk file
Detection ratio: 8 / 40 (Android:Hippo-D [Trj])
Second xxx.apk file
Detection ratio: 8 / 43 (a variant of Android/Adware.AirPush.C)
Nothing dangerous here. Hippo-D would be a nasty thing in mobile phones (because it tries to call/send txt messages to premium-rate phone numbers) and AirPush "is basically code in an app that pushes ads to your notifications bar".
