You are right, but still using an operating system with such large attack surface like Windows is a worldwide industry problem. No one is saying Linux is much better either, but there are other solutions like IncludeOS(http://www.includeos.org/technology.html#security http://www.includeos.org/technology.html#security) which has a very low attack surface, if not 100% impossible. I'm not saying IncludeOS would work in this case, but secure systems has come a loooong way the recent years.
