you're not supposed to have anything else than what was restored. So surely no later updates (what updates?) and nothing you installed yourself in Config Panel>Add/remove (just the things that were there already when you bought the machine in 2004).
It's not clear to me what you have done exactly, and what the current status of your PC is.
For security you need a two-sided firewall, an antivirus and at least one antispyware solution. For all of these there are free ones and others you've got to pay for.
And, of course, after a restore back to 2004, you might need to reinstall the XP SP2 update to start with, if that wasn't included then.
So please tell more.
