rootkit redirecting
recently i experienced some kind of rootkit on my windows pc, in a manner that almost every webpage i tried to go to, it loaded the webpage wkpg.org. i tried for a long time to get rid of it but ended up formating my entire harddrive using gparted from linux, and im now in the process of reinstalling windows and im sure problem willbeen solved, but also more annoyingly is that at the same time my pc started doing this, my iphone did aswell... i have done a full erase of my iphone twice now and the problem still exists, being redirected to wpkg.org, this happens not only in the browser but in apps too like stumbleupon... what can i do?
iPhone 5s, iOS 8.3
