Has anyone identified a security product that actually prevents the Crypto Wall virus from infecting a computer/server/network. I've seen anti-virus products identify it and even remove it, but not before it's already encrypted thousands of files on the infected computer and any mapped network drives. I've had two customers fall victim to this evil virus, and I had to stay up all night both times restoring files from backups. Fortunately, I had good backups in both cases. Otherwise, the customers would have been screwed.
Besides having backups to restore from, is there any way to defend against this threat?
I've seen some best practices out there, but I'm just wondering if anyone knows of a security product or service that has demonstrated success against Crypto Wall.
