Hello. A couple days ago, I noticed something odd in my iPhone's safari history. I noticed entries that said (no title). When I check on it, it either has a URL that says ads.pubmatic.com or it covers up a website I visited previously. I'm concerned there may be an infection or something. I used "Clear cookies and data" from the iPhone's settings menu. I don't know if that'll make any difference. Is this a serious problem and what can I do? Does anyone know how I can determine if my phone is clean and would it be safe to connect it to a computer at this time? Thanks.
