This question relates to my Android system phone. I just bought the phone four months ago. I have only used it with my home WiFi (parents' house - not dorm or apartment) for three months and really only occasionally surf the web at super safe sites and/or use email on it. Anyhow, a couple of weeks ago (around the time my laptop "died" and went into some weird infinite loop after a Windows update for those who recall that other thread), I was surfing the web on my phone and what seemed to be an entirely new full-screen page popped up out of nowhere. It wanted me to go to some other page IIRC. It looked really suspicious and I didn't click on anything and instead closed all the browser pages. I think (IIRC) as I closed the pages that another page may have popped up too. I never clicked on those weird full-screen pop up pages though. I just closed stuff. Then I turned off WiFi immediately. I thought it may have been some kind of malware. Question: What's the likelihood that these sorts of pop-up pages happen if they are NOT malware? I'm scared to use WiFi on that phone again and only use my other back-up phone currently. Do these ads always indicate malware pretty much? I don't recall my finger slipping (and accidentally clicking on something) while browsing online for this weird page to have popped up. IIRC, I was reading something and it just popped up out of nowhere.
