Tom, I didn't say that I doubted Flash could let infections onto the computer. I was asking how he seemed so certain that Flash was the exact culprit of this instance. It's usually very difficult to figure out when a virus made its way in.

That said, I agree with your conclusion. I recommend Chrome to all my clients, and one of the reasons is that I'm more certain that they'll be running the most recent versions of their browser, Flash, and Acrobat (which I try to get them to uninstall as well).
