UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Support Trojan in one of my files?

I am all of a sudden getting a trojan message when I access my admin panel.

I use Avast anti-virus software and it detects the following:

JS: Classloader-6
http://toolbarurl.biz/dll/loaderv679.jar/Counter.class

My server anit-virus software has not detected anything but there must be something up.

Can anyone help or advise?

got a link to your site? most likely it's loaded on your computer and it's being triggered by your web activity.
