Not being familiar with how a web-server works means that you are inexperienced, not dumb. Having Norton on your system doesn't do anything to protect your web pages, since your web pages are not being hosted from your computer. In the same vein, no software that you install on your system is going to tell you who has been goofing around on your server.
You have a couple of options. First, you get in contact with Yahoo or Geocities, or whomever is your host, and tell them what is happening. They are the ones with the resources to find out who has hacked your pages. Just seeing who the visitors are is not going to help, unless you know the exact time content on the site was changed. Making some wild guesses, their entire server is compromised. There is nothing you can do to defend against that. So your other choice is to change providers. Most people get free web space from their service providers (as long as it is not pornographic, commercial, etc), so that might be a better option.
