Combofix along with Malwarebytes is able to get rid of this nasty trojan/rootkit.
Go to http://www.bleepingcomputer.com/combofix/
but be careful if you go it alone, read the tutorial a couple of times. You should ideally use it under guidance as it can brick your system if you make a wrong move.
Just be carefull
allthough it`s worth trying as i would not do any online activity which involves passwords until it gave the all clear(or you formatted)
Also if you do download combofix make sure it is from the above site of from forospyware.com
There are a few sites with combofix in the name that are not legit
