On your homepage, at the bottom before the </body> tag is a block of obfuscated javascript, the block starts out

var dgBqgoMgsSHWTyZTDkNE

this block of script is malicious. heck all your pages for this code and remove it.

Do a scan of your PC and make sure there are no Trojans/viruses capturing your ids/passwords, change ALL passwords especiallly FTP, it is likely your passwords have been compromised. Never store/save your passwords in your FTP client, use secure FTP if available.

Once the site is secure and clean you need to submit a request for review in you Google WMT account to have the warning removed. If you have not verified ownership of the site you will have to do so first. The following reference explains the procedure.
