Please submit updated sitemap in Google webmaster tools.

Already did as my plugin automatically pings google but still its not going

Submitting a new sitemap is unlikely to remove a non-existing link. Did you try the link that @m_hutley gave - in particular the one that says Remove information from Google??

5 posts were split to a new topic: My site may have been hacked

Im confuse …exactly what Ive to do in this case

A good start would be to read the article.

But of course, you now have a different problem so this thread is becoming a confusing mix of 2 separate issues.

Edit: Your site having possibly been hacked probably makes this topic of somewhat less importance for now.
