crawl errors on blog footer from wordpress

Hi ! I seem to have 404 crawl errors on my blog and these urls were not done by me because they are in the footer and are related to comments that I did not cofigure. I cant seem to work out why these errors occur and how to change them.

hope you can help as Im finding wordpress very tough going and I have only 2 pages in it.
