Anyone tried this?

It's basically windows defender (anti spyware), anti-virus, windows updates, windows server security all rolled into one, and centrally managed, and can be deployed in a domain environment to all PCs using a windows sus (update) server, or installed on stand-alone (home) PCs...

so if a pc on the network had a virus it would report to a central server...
