I noticed a couple of people recently with this virus so i thought i shall put this up.
Firstly you will want this program.
http://malwarebytes.org/Install this then run a scan and it should remove it first time. If it doesnt then you will want to try the next program on the list.

This link contains a thread on how to remove it. If malwarebytes doesnt remove(it should easily) Then this probably will.
