disordering xperia p

[reza8]

Hello my xperia p has been disordered.Its data traffic and wi-fi are turned on without my permission.My phone begins to download automatically unwanted files and apps and it wants to guide me to sexy browser and links.Two weeks ago I wanted to root my phone and after that these happened.After I delete the unwanted apps and files, they come back and are installed again.During working an app it goes away suddenly.Several times I did Reset Factory but didnt help. Please help me thank you

I think after factory reset u install infected app or see infected site
Go setting,,, security,,, device administrators
See what apps have permision
If any suspected app in the list selected ( if selected in the list) deactive it and go too app list then unistall it
See and feedback
It cuased by some adware apps and i saw this problem in 2 phones and both have same problem
Sorry for bad english

Instead of factory reset, do a complete wipe and repair installation in pc companion.
