Trojan Horse has taken over my computer

I have used Spybot S&D to detect and remove what appears to be a Trojan Horse. I am getting dozens of pop-ups within a span of 30 seconds, and the start page of the web browser keeps resetting automatically to a blank page. Please let me know if you can offer any suggestions.
