Just a note:
Windows vs Linux Security is an interesting topic.
There is much that can be exchanged in the way of ideas.
Starting a new topic to cover it may be worthwhile. It currently is a tangent in this thread but at its current progress, may be difficult to separate out since it started from a user pointing out it was a reason that they had for switching.
To this end:
Please post Security related responses in the new thread so we can keep this one reasonably on topic.
