Malware injection in site, how to remedy?

Question

I have a big problem. The website that I look after has gotten infected. That being said, my problem is that I cannot find the source of this infection. My javascript files appear to be clean. My PHP is clean. The weird thing is that the injection occurs in all the .html files as well as in all the .php files. My .php has no link to any other outside scripts. So, it can't be the javascript, right?

this is the example that I get:

This is my page: http://www.activewatch.info/

I am using a hosting plan from godaddy (if that helps)

I am interested about finding out if my server is the problem or if it is the files I have uploaded.

Your opinions are greatly appreciated. Thank you.

Ps, I 've posted this on google support forums and sent an email to my host, explaining my situation.
