searchqu.com/406 removal

I seem to have a virus or something that changes the home page of my browsers to searchqu.com/406 no matter how many times I change them back to my preferences. I have NIS 2011 and have run couple  full scans but it doesn't seem to remove this virus-program. Has anyone else had problems with this virus-program and if so how did you get it removed?? I did make sure my NIS 2011 had the newest virus definitions before running the full searches.

 

Thanks to anyone that can be of help to me on this subject
