Graphics, User Interfaces "What if all software was open source? Anybody would then be able to add custom features to Microsoft Word, Adobe Photoshop, Apple iTunes or any other program. A University of Washington project may make this possible." Yeah I know, odd headline - couldn't find anything better.

If programs were all open source it does not neccessary mean they are easier exploitable through malware. It is because of the operating system's security model.

If you look at say Linux which is open source it does not have malware problems and that is _probably_ due to a better security model compared to say Windows which is famous for its malware. I say probably because I'm not sure of how the Windows security model exactly operates but I'm pretty sure you have the ability to install programs as a normal user which is the main reason behind the problem.

Yes, you aren't sure of Windows' security model. It's similar to Unix, although a little bit more orthogonal. All kernel and system objects are protected by access control lists. Permissions cascade for hierarchical object systems. It has user, group and everybody permissions as well, just like Unix (although the UI makes it look more complicated).

As a normal user on any NT-based version of Windows, you can't install software, unless given permission to do so. The problem pre-Vista was that the default user was usually the administrator (=root). As such, regular end users (as opposed to user accounts) could install software with out privilege escalation. Thankfully, this policy has been reversed for Vista and 7.
