I was/am one of those people. For some reason using MSE rings of having the fox watching the hen house. That said, this machine has MSE on it, as does most of the rest of my equipment, and I've been recommending it to anyone that needs a freebie AV product for residential application. I've *never* had an issue, and *never* gotten a box back sick. But, time will tell. It's certainly an upgrade over the current iteration of AVG Free.
