you got blacklisted for a reason. check your site really well:

  • get tool like fiddler, open your page in web browser and make sure requests sent from your computer go just to your site [ or trusted 3rd party sites ]
  • open all index.html/php in text editor, turn on wrapping and search for rogue javascript / html code.
  • check content of .htaccess files and make sure they do not contain any malicious rewrite / redirection rules

there is a plague of programs stealing passwords from ftp clients and uploading rough html / javascript / .htaccess files.

or maybe you just got hacked / are victim of js/html injection to your cms.

I actually notified a friend of mine the other day that her site got blacklisted the same way. I looked through the source code on her index and she had shady looking obfuscated javascript in her head tag. I think this is generally the reason this happens. Someone compromised your website and you need to find where the problem is as soon as possible.

So it was rogue javascript? In order to fix this so you are no longer blacklisted, read this google.com/support/webmasters/bin/… After you follow the directions there, and google looks through your site and verifies the malware is gone, they will remove you from the blacklist. You should also read through this blog entry: googleonlinesecurity.blogspot.com/2009/10/show-me-malware.html –  Marcin Nov 21 '09 at 11:01
