Computer security partition?

[God-like]

Hello,
I have to make an application. I have a computer that does not want to be infected with viruses, important work, but I would like to use for other things. I thought that maybe I could partition the disk and create 1 account for partition so that in case of virus will infect only one part of the disc.
Tell me it is feasible such a thing? if you like? if no alternatives?

Do a dual boot Linux and uses to navigate the mountains or to limit Linux on a virtual machine.

I would do it but my brother is not able to use Linux and thus would be better to put xp. Can we put 2 xp?

There are several possible solutions:

1. Using account limited (99 & infection, at least those most series, which may password protected and other can "settle" in an account without government privileges)

2. use programs such as virtualization or Returnil Sandbox

3. Use Virtual PC or other program that can create a virtual machine to be used for navigation on Internet, download and install programs, do anything you want, and then use the only real operating system for safe operations, save important documents to be copied by VM (Virtual Machine)

I will recommend a mix between the example 1 and 2
