Malware on site, google blocks it - what to do - Help?

[q-skins.dk]

 

Hi Everybody. 

 

I got an mail from google in my webmastertool that my site have been infectede with malware, problem is that i don't know anything about deleting it? In my webmastertool it stands that the file google found with malware was http://q-skins.dk/counter.php. I have never seen that counter file before so I have just deleted it but it still not work, my site is still blacklisted by google. 

 

I have no idea how to identify files with malware so what can I do? Are there not some kind of files or programs that can tell me which files is infected? 

 

 

Right now my site have been blacklisted for about 4 days, it is very frustrating and i think that i will have a negative influence for my google indexing - right?

 

Thanks in advance.
