sharify-style.php question

Just to give you more info:

90% of my visits look like this:

…visited http://mywebsite.com/mypage/

and then right away

left http://mywebsite.com/mypage/ and visited http://mywebsite.com/mypage/wp-content/plugins/sharify/sharify-style.php

which makes no sense, a visitor should have end up on that page

Wordfence was the only plugin updated couple of days ago, I already posted on their forum to see if there is a compatibility issue, but appreciate if you could look into this as well.

Thanks
