Trojan.Vundo removal

I am having a serious issue of trying to remove trojan.vundo.  Everytime i start up the computer a quick scan is run and finds the virus.  I "take action" and then need to reboot to solve the problem.  I then reboot and it does a quick scan and finds the virus again.  Why can it not get rid of it?  I've tryed the FixVundo.exe from symantec and it runs but doesn't find anything.

 

What can I do to get rid of this pesky thing?
