Here's what worked for me, regarding the White Trader thing, in case anyone's Googling.
Was going out of my mind last night, trying to get rid of this thing. I think that "White trader" is a very specific, sophisticated, new rookit, because none of the other programs were able to clean it out. Most didn't even detect it.
Malware Bytes' anti-rookit program was the only thing that worked for me.
Malware Bytes' normal version didn't work for me, and neither did Norton, Adaware, or TDSSKiller (though they all found some stuff, and cleaned some stuff...White Trader was a persistent little thing!).
Thankfully, the Malware Bytes anti-rookit program is free, but it is in Beta form, so use at your own risk. I personally had no problem with it, and it was the only thing that got rid of this annoying thing.
I'd recommend downloading it directly from Malware Bytes, rather than cnet or anywhere else, because Malware Bytes has the most updated version. I ended up having to go there to get the most updated one anyway.
Good luck, and let me know if it worked for you as well!
