My websites is hacked and IP is on a Spam Blacklist

Hi everyone!
I created a wordpress blog few months ago and left updating it, because i was busy in other things. Today when i tried to log in to my wordpress i received a message
<b>Your IP is on a Spam Blacklist.<b>

When i visited my blog i saw a anchor text link right under my logo and i never put it there.

Now i can’t log in to my WordPress and my Ip is added to spam list.

I,m worried, what should i do to remove the anchor text link and to clear the spam allegation. Your help will be highly appreciated thanks in advance and sorry for bearing my bad English.
