trojan.gen.2. - Help!

Hey,

 

First off I don't understand any of this.  I got the virus but Norton is saying my computer is fine.  What's happening is the virus keeps looping and showing quarantine, deleted,  status infected.  I called the support line and was told I needed to pay money cause my configuration files had been stopped. But, they didn't say anything about removing the Trojan.  I told them when I tried to use there removal tool I got a error message 404.  He never talked about removing the Trojan.  Why?
