Website with a virus.

Hey, so I was looking through safari, and I wanted to get a YouTube music video and convert it to an mp3. So then I went to the website ytmp. Once I clicked convert, it sent me to another website, and I was told that this website has viruses. It’s not the fake warning we all know about with the grammatical errors. It seemed like a legit warning from apple, and ask me if I wanted to continue. I immediately get out of that website, and did it all in my computer. No problem. But I’m still pretty scared that my phone might have a virus.
