Why is formating showing up in Safari suddenly?

So, I just realized that Formating (as in formal formating, like the little symbol to represent “paragraph” not like HTML or something) is showing up all over the place in Safari. It wasn’t doing it an hour ago, now suddenly it feels necessary to show my were ever space is and every place the developer of any website, hit “return.”
I must say it is a surreal thing to experience, but now the novelty is gone.
How do I make this stuff go away, and why did it just show up? Could it be a virus and\or spy-wear? (I was just surfing some website of ill repute, [Not porn but hacker’s sites])
and if it is spywear… WTH?!?!?! I mean, besides the fact that I am used to seeing this formating in my writing, is this supposed to be “destructive?” Cause if it is, I would mark it as a FAIL.
