the last HJT report was AFTER the scans and norton removal correct? The reason i ask is because you still have all the adware running in the report and the leftovers of Norton antivirus. I would have expected Superantispyware to do better than that. If it is not a new HJT report, please post a new one (make sure to overwrite the old report when saving the report or name it something different and upload it).
Vundo is an especially nasty type of adware that is very common. The good news, its very common so many programs can remove it. The bad news, its famous for a reason because its constantly evolving and infecting many computers.
