Malware was found on the forum - looking for advice / help

[losasso]

One of my forums was hacked few days ago.

practical machinist .com

Google Webmaster tools keeps telling me that this code is present on my pages, but when i view the code, its nowhere to be found. It looks like its showing randomly on the forum and I never found it on any of the pages.

###script type="text / avascript" src="http://www. erikymkzf. co.
cc/ build.....? var"###

(original code is broken with spaces - not to be crackable)

- I checked Footer, header code, camper it with the test version we have for the website, nothing was found there.

- I run virus scan on the server - nothing was found

- We looked for that code in all files on the server - it was not found

- I also have VBSEO that I'm updating now and few Ad Managment modules that appear to be ok.

At that point we are not sure where to look and how to troubleshoot the problem

If anybody can help we are ready to pay.

Thank you
