I have been using Comodo Internet Security since it’s initial release and it just keeps getting better and better. However whilst trying to install the most recent version 4.0 which was released on March 03 2010 I encountered an installation error 1603. Naturally I cleared all the junk files, disabled unnecessary services, cleared the registry and still couldn’t get it to work

Comodo firewall has been around for a few years now. It has always been rated highly for its tough firewall. Version 3 now comes with a Host Intrusion Prevention System (H.I.P.S) in the form of Defense +, which protects critical operating system files, the windows registry and personal data by preventing unauthorised access. It is extremely useful but can often be bewildering when all these pop-ups keep appearing on your screen, especially if the user is an amateur and doesn’t understand what is being asked of them. However, once you have got used to it, it works like a dream and doesn’t take up too much memory.
