The UNIX factor (Score 1)

I'm not really an OSX user, but I do have quite a bit of experience Linux and I know that they have the same base: UNIX. I know that in Linux all of the data pertaining to one user is stored in the /home/user directory. If the same hold true for Mac OSX, then couldn't you just eliminate all the spyware by cleaning out the /home/user/bin directory of all unwanted programs and then delete their associated files in the /home/user directory? Or is their a way for this malware to do a root level install and make it's home in the /usr/bin or similar directory? And how would they gain rool level access in the first place?! Sounds like user apathy to secure their boxes.

I'm sorry if I came off a little trollish. I just wanted to point out one of the main features of UNIX that should prevent any intervention in the form of malware ever being permanetly installed on the computer.
