demo sites

I need to provide a demo of different components of untangle to one of the owners of a small business in the next few days. I have been running untangle for a couple of weeks and love it. it has stopped spam completely, I am running premium version.
showing spam blocking result is easy, but it would be interesting to show adblocker/virus blocker in live, with or without untangle. Does anyone know any site that would infect a computer without untangle but would get blocked with untangle.

thank you.

I know of a site that is full of older malware in downloadable file form that with Kaspersky and Clam you would catch 90% of the malware, but some may get by.
