Bookmark with bank log-in created by someone else

I noticed an Other Bookmarks folder in my bar yesterday. Clicking on it showed 3 bookmarks: One labeled as move: https://www.lyricsondemand.com/tvthemes/rawhidelyrics.html One for Google And one for my bank account with log in information all filled in so that you only had to click submit to get into my bank account I didn't create any of these. What is most disturbing is my bookmark for my bank account log in is first enter username, hit submit, then password is auto-filled in the next screen, hit submit to log in and see account details. Again, I didn't create any of these!!! How can I see when they were created? Can I see how they were created? Anything else? This is of course very disturbing! I have changed my log in and password and checked off every notification feature in my online banking privacy area. Thank you Shaun
