Fake article posted on Facebook-Can it cause a virus??

I clicked on a supposed article my friend posted on Facebook via my IPhone 4s, and realized that it was not legit. I have then received failure Demon notifications in my yahoo mail account. I’m guessing it’s a virus?? How do I remove this? I only ever access my email through my iPhone. I’m a bit worried that security gas been compromised.
