I keep getting an Android homepage hijack using Chrome. "You won an iPhone" etc. I can get out of it but can't make it go away permanently. I don't want to factory wipe and can't seem to find anything that works. Trend Micro, Avast, and many more. Galaxy 6, latest update, stock. I have erased history to the beginning of time leaving only passwords but the hijack only goes away for a while and then haunts me again. Anyone have any ideas?
