Virus-like behavior with website through Safari
When I go to a local tv station website through Safari on my iPhone 6s, I get a number of pop ups after I click on and begin reading a news story. The final pop up that appears has been pornographic. I have questioned if my phone has a virus, but have been told that iPhones do not get viruses. My iPhone is not jailbroken.
I believe this behavior happens the first time that I go to that tv station website each day or possibly only after I haven't been to the website for several hours. Subsequent visits to the website immediately after the pop up behavior occurs results in expected website and viewing of news story behaviors without the pop ups. I also believe it has only happened when I visit this one particular website. I do not have the same behavior when visiting that same website from my iPad, MacBook, or iMac --- only on my iPhone. I have also cleared my history and website data for Safari through the settings app.
Any suggestions on what this is and how to fix it? Thank you!
iPhone 6s, iOS 10.1.1
