Its all about architecture. It is rather difficult to make a virus for a Unix based operating system. It is really easy ot make one in windows as Outlook express executes things within the application's background. People should just stop using Outlook/Outlook express because macro viruses are run within emails as scripts and can run in the background and such. Its really the arrchitecture of windows that is the issue. Microsoft knows this, but isn't donig a whole lot to fix it. Sure XP is stable, but theres enough ot go wrong as wo where it can be a real mess. Microsoft is losing corporate business because of this. Their next major OS revision will have a new architecture... but who knows when that will be out.... I bet 2006...
