VIRUS ISSUE WITH http://www.hetzner.de/en/ HELP NEED

Hello
I have couple of server with http://www.hetzner.de/en/ and i have big problem. I am getting complain that my IP is use for spam and virus attack. I am request hosting to provide me PATH of file so i will delete that but they are not providing any path and it is really hard time to find that file in 4 GB file storage.
can you please tell me any free tool that can scan and find the file for me ? It is really high security compromise by hosting company.
