Karnac, it would be appreciated if you don't tell people to start removing harmless files without explaining why they might want to consider removing it. Thanks. I'm not trying to be rude, but you're not exactly qualified to handle HJT logs. And for the record, telling someone to basically find a couple of arbitrary registry files and delete them is generally frowned upon.
John, I've got a couple of questions for you. Since running these scans, is Avast still detecting rootkits? If so, could you please post the log for it? Or do you have an old log by any chance? Various unwanted files were removed, but I have no way of knowing if they are the same files being detected by Avast.
Also, the removal tool posted by Karnac should help out with removing Norton. If you still have trouble, we have a brief tutorial in our FAQ's that I can direct you to.
