weird url problem

Hello

I have setup my first blog on site rightcopywriter

Everything is running fine but I just tried to create a google sitemap for my site and found below links

http://www.rightcopywriter.com/blog/wp-login.php?redirect_to=http://www.rightcopywriter.com/blog/news/microsoft-ties-with-yume-for-video-advertising.html

http://www.rightcopywriter.com/blog/wp-login.php?redirect_to=http://www.rightcopywriter.com/blog/news/microsoft-search-centre-in-europe.html

There are more of such urls and I don’t know what they are

Can anybody please explain me are they good or bad, why aren’t they redirecting and how do I get rid of them

Please help

Thanks
