Can I use NetGuard with Vista?
For the time being, your NetGuard service is not compatible with Vista, Microsoft’s latest version of Windows. If you’re thinking of upgrading your computer to Windows Vista, please be aware that Netguard will not work and you should not try to install it. We’re sorry about this problem and rest assured we’re working hard to make NetGuard compliant and will let you know when it is. In the meantime, you can find out more at www.virginmedia.
