Re: Good Programs
Unlike *most* other operating systems, MS products install everything in the system directories (in fact, this is the only way they can run). Even worse, runtime information is contained in the system registry!?! If the architecture was set up so that a pointer to the application's path is stored there, and then the application is responsible for it's tree (ie: root, root/bin, root/lib, root/etc...), it would be absurdly simply to quarantine any installed program (as well as completely nuke it if desired). In addition, any program could be set up to only have access to the files owned by the installer (who *usually* should not have admin rights to the entire system tree.
This way, *no* malicious program would be able to modify system (or other application) libraries at will.
