I'm not sure where to start here. I think you should not have waited as long but you probably already know that. What is it that you download to scan with? Perhaps if you checked add/remove programs in the control panel for some things that you don't recognize. Can you get into there at all? Another possiblity would be trying to get to system restore and go back to a time before you got infected. It may not remove everything but it might help enough to get some scanners downloaded at working. You could also try going into safe mode and scanning with whatever you are scanning with.
