Back to using SteadyState, Deep Freeze or similar product
Windows SteadyState runs on WInXP and is free. I don't know if it runs on Win7/8. Once can also use DeepFreeze. I mean these will defeat all viruses and malware and I have often wondered, how these products did not cripple the AV industry and render them almost irrelevant. It seems like they were never widely adopted. But that is the prevention side of it. And then to defeat the infected, one could possibly use ERD Commander. Many years ago I contemplated creating a network which could not be infected. It seemed possible, but at the time the features and resources did not exist. Today one company has already built one part. I am shocked and amazed and disappointed that it was not my company. That it was even possible was a joke with my friends. And part of it involved creating a complete mirrored virtual network. Users would work the on virtual network, with something like deepfreeze and IDS/IPS and then only secure scanned files could be saved to the physical network. There are a few more pieces to it, but too much to detail here. I hope if someone beats me to whole deal, they will invite me to work for the company:)
