Qubes OS

Qubes OS is a security-focused desktop operating system that aims to provide security through isolation. Virtualization is performed by Xen, and user environments are based on Fedora.
In order to secure a desktop, a Qubes user should take care of isolating various environments, so that if one of the components get compromised, the malicious software would get access to only the data inside that environment.

So why haven't you switched to Qubes OS yet?
