Tell me just one thing

Why modern OS security is based on file permissions? Why not base it on what user passes to a program? If I pass a file to a function, then it has access to it. That way no malware can open backdoor without my explicit actions. It's that simple! Unix designer must be retard, it's good he is dead.

Its better to prepare to fail, rather than fail to prepare. The ability of any software which runs with "admin rights" on Linux/Mac/Windows to deal any form of damage is defective by design. If you can't see that The Right Thing is to deny access to everything by default, rather than allowing the malware to rape your PC by default.
Any performance cost will be negligible compared to reformatting your own disk and restoring backups. Just think about what is your "Spirit of the Right Thing".
