Last day when i visited google webmaster tools, i found crawler errors for 42 not found pages. all the pages were having "luminous-solutions.net" at last in the URL. Like
http://article-stack.com/2010/08/page/luminous-solutions.net
I had never written any post which is having this word. For the safety, i had manually searched it on my site using internal and external search facility. I also had searched in source code as well.
I had searched in database, newly installed plugins, theme code.... But i found nothing with "luminous-solutions.net"
404 means, some text in contents are pointing to these links. But link doesn't exist. I had manually checked those pages as well.
May this fault occurred from google crawler itself or really some virus infected my site?
