How to remove Black-listed problem from website?

First of all you need to check your google webmaster for the notification.. that whether your website is blacklisted or not... once you confirmed that, then you can remove all the bad things which you have done like disavow all backlinks, write frech content and then submit your website for re-consideration to google.
 
Your website is blacklisted because Google scanned your site and found harmful behavior. Google needs to protect its users from dangerous websites that show up in their search results. In fact, websites that repeatedly get blacklisted for malicious behavior are limited to only one review every 30 days. That big red splash page (and warnings next to your site in Google's search results) are designed to stop visitors from entering your site. It works, too. Websites lose about 95% of their traffic when blacklisted by Google.
