Avoid visiting suspicious sites
You can use a web browser on your iPhone 8 to surf websites just as you can on a PC. If you are not cautious when visiting websites, malware or viruses may be put into your device. Some links on a website may be booby-trapped, allowing viruses to proliferate and take control of your device once you click on them. The same may be said for malware that operates through email. In general, only click on a link that comes from a reputable source. Avoid clicking on anything if the website or email link appears to be shady.
