There are a number of programs that are available to block out all the internet crap. This is a link to one that has received some praise.

You do need to be really careful though, My daughter is now 20 but she has been using the internet since she was 11 or so. I did not use any programs back then but I did take a couple of precautions.
- Ensure pop up stopper is enabled & windows security updates are set to automatic.
- Set Privacy control to high (Tools, Internet Options, Privacy)
- Never allow the child to install a program without checking with you first.
- Put the computer in an area where you can keep an eye on what's going on.
- Show an interest in what they are doing - monitor their activity, don't spy.
- Tell the child that they are not allowed to tell anyone personal information, name, address, phone number, even in an email.
I've had no problems with these preacautions in place.
Windows XP has other controls built into it that Win 98 didn't, so you can do things like set up another account that restricts access to certain functions of the computer but you do need to be a little savvy to use them.
Good luck
