This was configurable, but it wasn't a straightforward task. The Parental Control feature isn't the most effective on the market, but it's adequate for most family needs. You can decide which categories to block, choosing from a database. Or you can block everything and then specify which sites can be visited. Free updates to the database are available for the first year, after which you have to fork out for subsequent updates.

The package also comes with a full copy of Norton AntiVirus 2000, a competent antivirus product. This has one or two new features, one of which is designed to trap viruses being transmitted as email attachments, perhaps the most common vehicle for their distribution. When you install NAV 2000, you have to specify which of your mail clients you want to protect. We installed it, and then found our email link to the Microsoft Network had been broken. MSN uses a Microsoft security oddity called Secure Password Authentication, and it was this which thwarted the protection system.
