Help removing nginx Redirect Virus

My computer is 9 days old and I have managed to get this virus. I removed/uninstalled every strange toolbar that I had and ran a full virus scan. I no longer get that welcome to nginx page, but I am afraid the virus is still in here.

 

I am using a HP computer with windows 7 and firefox. I also have IE and Chrome..but seldom use them.

 

I am afraid to attempt alone, any online fixes that I have found..please help.
