Looks like your trojan comes from some advertisement placed on ygakud.us.to.
My anti virus software detects it every time I come to the oxwall website ,put avg on your computer and see for yourself .it must be on the oxwall website .It is detecting the trojen horse object name ,not a website ,and the only way it can do this if it is on this website.Some one has put an image on this website ,and renamed it to look like its from another website.It may also be a link in some code on the oxwall website.
