You shouldn't worry about that affecting your ranking, here is an explanation of Matt Cutts [this video] about this topic and to my knowledge this is still the same. The only thing you should worry about is your data, you should stop this Referrer Spam and check for more.

No, you won't get better results simply from using Google Analytics and Google doesn't favour sites with Google Analytics over sites without it installed. Google Analytics is of course a great analytic tool and when the data is studied correctly, it can influence on your SEO efforts and thus can indirectly affect your SEO. (As could any other types of traffic analytics software) But simply installing Google Analytics wont give you any kind of SEO 'boost'. Here is Matt Cutts, head of Web spam at Google, confiming this: Will using Google Analytics have a negative effect on my ranking? [this video]

No, it does not. Your Google Analytics [this video] is not a ranking factor. So garbage referrals, or anything else in your analytics, will not affect your ranking.
