This is not entirely true. In most home computer cases, a user with admin privileges is logged on all the time. Now just because the user has admin privileges does not mean they have full System Admin privileges. This just means they are allowed certain privileges to run and alter programs, not the system files itself. Now if a program were to affect a system file or the system folder, it would ask the user for an admin login and password. So in essence, you would know if something were trying to access your system.
Terminal (or Darwin, the Unix core) on the otherhand is a bit different. I am not too entirely familiar with it but I am learning. From what I understand, you do have more access privileges in the Terminal than in OS X. But Unix is a bit more of a powerful operating system so that does not surprise me.
And to straighten something out . . . Mac OS X is built off of a Unix core, which means that OS X is not entirely Unix. Therefore you can attempt to infect your OS X box with a Unix "virus" unless u tried to running Terminal. Nor can you (from my understanding) infect OS X with a "virus" (if you can find one) from Unix, this case the Terminal.
If I am wrong on any of this, someone please point out my error. I am here to learn just as any other.
