I need instructions on how to fix a problem of accessing the Internet. I keep getting blocked by I believe it to be Google, telling me that every site I want to go to is unsafe.  It gives me 2 options, one being advanced. I tap on advanced, then the sites address appears, I tap on that, and I am allowed access. My wife does not know what she did or if she changed any of the settings. Please help me, because she thinks there is another person or thing taking control of her phone.
