i bought my child am android phone from a DX.com.good specs for the price , the phone is KINGWILL 5 inch. suddenly we start seeing apps/icons on home screens , which some are inappropriate. at first i thought the kid did that, but after uninstalling them, deleting icons, they kept coming back. some where just games and some were links or apps of pornographic sites. i installed AVAST and AppBrain Add detector to see which apps were installing these other apps . some of the apps on my machine are in chinese and i dont understand them, and i have a lot of icons that have the android symbol and i dont know which are necessary for the OS of the phone and which are mallware. i guess something has rooted me. pls help how to figure this out . (i have 4.2.2 android OS). PLS HELP
