Security issues, such as viruses and trojans, are one of the reasons why I am working on changing my O/S to a *nix based one, like Red Hat Linux v9. They are more or less immune to viruses
Too bad so many Windows apps I could not live without do not work with such O/S’es. I will have to learn more about Windows emulators in the *nix environment before I swap over. Might still want to keep a dual-boot system.
BTW, does anyone have a link which describes the entire Terminal window command set for Linux or FreeBSD?
