Cannot remove backdoor.hupigon and hacktool.freezer from SBS 2003

I need assistance with removing malware from a clients server. They are running MS SBS 2003 SP2 and unfortunately were only scanning Exchange for virus activity and the server has become infected with a number of trojans and backdoors. I have used RootKitRevealer and AutoRuns to identify the problems and Spyware Detector from MaxSecure has cleaned most of them. Two infections keep reappearing, backdoor.hupigon and hacktool.freezer. Does anyone know how these can be manually cleaned from the server?
