Browser redirect after iphone reset
So I am having issues with my browser redirecting to sketchy websites from perfectly safe websites for the last couple days. I tried deleting data from safari, turning my phone off and on again, and so forth. none of this worked. I ended up factory resetting my phone and restoring it to a backup from May. On the second tab I open I am redirected to one of the sites from before telling me I have five minutes before all my data is stolen and I have to download their software.
Both tabs opened were to D20PFSRD a reasonably respected pen and paper RPG Wiki.
I am wondering are there any further steps I can take besides burning the phone and burying it in sanctified ground.

funnily enough the above picture I was sent to after posting this
