Try denying access to the Google Robots. You might have given access to Google Robots to crawl all the files. If it doesn't work either then you will have to remove the data or file that has been detected by Google.
What does this help? You let the malware sit on your site and spread to other users computers. What's your domain name?
Without knowing your site, or seeing the malware (malscript as I call them), it's difficult to advise you. However, in general, many of the recent websites have been hacked by using valid, stolen FTP login credentials. The hackers obtain these by a virus/trojan on a PC with FTP access to a website. These FTP login credentials are sent to a server which carries out the infection of the website. Part of the infection is to add files to the website that allow the hacker to remotely infect the website after the FTP passwords have been changed. Look inside all .php files for a string that starts with: <?php eval(base64_decode('aWYo and then continues on for a long line. You might also have a file in all images folders that's called gifimg.php. You can Google gifimg.php and you'll see my blog posting covering this infection. Mine is the first listing for that search term. I use grepWin to find and remove these infections. (and it's free!) Post back here if you have any questions about removing this or PM me.
What kind of malware? Look into the HTML source for weird codes like iframe or script which you not suppose to have. Anyway, the very important step to keep your site safe - don't save password in FTP softwares. More info
