"How to make sure my phone doesn’t have a virus: Hello everyone! I was doing some surfing in Safari one night trying to watch SpiderMan Across the Spider-verse, and I get a pop-up saying my IPhone has 19 DIFFERENT VIRUSES. I am seriously scared for my privacy and safety on this phone, as I do not know whether to believe it or not. Some help or reassurance would be nice. Really hoping I don’t have to get rid of this phone."
