manleystanley is right.

I don't know about the new DAZ installers, but the older installers were reporting personal information on pre Win 7 machines. After Win 7 came out there was a mistake in the installer that revealed two web pages, showing the personal data that was being transmitted, including the IP address, while installing the product. In pre Win 7 machines there would be a quick flash on the screen, but the customer proabably wouldn't have noticed. It was more than likely a third party company that reported to DAZ the personal statistical information. Even if you didn't run the browser the info still went out. That might be why the antiV pops up for some people, such as manleystanley.
