From a piece of code found here: htxp://xorl.wordpress.com/2009/02/26/trojanizing-gnome-and-kde-desktop-files/
I then got a website alert from the avast shield sign of HTML:script inf found and connection was reset,
well done avast found it before I could…even if I try to load it at jsunpack I get the full avast alert and
disconnect: this time it is found as JS:Downloader-LP [Trj] in …dec/go
