Internet security is serious business, and the Comodo application will allow users to feel a bit more at ease. First-time users can use their help files to learn a bit more about the various uses of the application, and others will note that the different sections (which include "Firewall" and "Defense") are fairly intuitive. This latest version includes DNS protection and it also checks the integrity of every file and application which asks for access to users' computers. This version is compatible with computers running Windows XP or Vista.
