Easy Inline?

I just went to reply to a comment on my opening post for the Palisades Shore series, and lo and behold there are these double-underlined pop-up links there.  I noticed the same when I was reading elsewhere on the net.  So quick question -- did I inadvertantly install some sort of "helpful" junk on my computer lately, or has Blogger foisted this upon my blog? 

I know I don't want this linked to my content, that's for sure.
