I want to know how to block this website

Okay, so I was making a video on Kinemaster and needed a sound to used, so I inputted a sound to a YouTube to MP3 downloader. It usually has redirects, just to note. When I was redirected, it took me to a website named SHAXON.*SHOP. It said my IPhone was hacked. I went on the same website on my Chromebook, and nothing popped up. I know it's a fake website used to make you scared, but I want to know how to block this website, because it is incredibly annoying. Thank you!
