Need direction for issues with Malicious Javascript Encoder 5 on my webserver, What next?

Need some assistance please.

I have a web site hosted by GoDaddy.com. Starting around December I started getting alerts from my Norton products that a malicious JavaScript encoder 5 was detected on my site. I signed up with Norton Safe Web and Safeweb also states I have the malicious JavaScript Encoder 5.

 

I subscribed to Googles web master tools and it tells me the site is clean! Where do I go for help? No one can tell me where this JavaScript is located! Godaddy basically telling me it's my issue, not theirs. Googling the issue does not give me ANY solutions. Just a lot of talk about it.

 

Where can I find additional assistance? I would think that Symantec would have some type of product that could scan the site & tell me what files have the JavaScript.

 

Thanks All
