Cant get ride of a trojan?

recently i had a trojan that is called trojan.secup and norton deleted it but each time i switch on my computer and go to access the internet norton pops up saying this trojan is on my computer but it deletes it each time

Also i visited the symantec site and got info on this trojan and it is as follows, the trojan is a risk level one and the only thing that it does is give you false warnings saying that your computer is infected with trojan, virus, malware etc and that you should download the software that they are advertising all of these warnings come in the form of pop ups and icons on my system tray.

on my computer i have the latest version of norton antivirus which is completely up to date i also use bt/yahoo antispyware and aslo have ccleaner on my pc and still no good,

Any suggestions on what i need to do would be good as yahoo answers have been very helpful in the past thanks guys
