My view on linux being more secure than windows, is that for me, windows is far more securer than *nix because I know windows very well. With Linux I don't know it well enough yet, therefore I don't know how to secure it well.

So if you know *nix better than a windows box then the *nix is going to be more secure for you, but if you know windows more than *nix then the windows box is going to be more secure.

Sure theres more viruses for windows than *nix, but believe me, *nix is still susceptible.
