I just love how on Windows almost all apps require admin access, so basically it's worth nothing. Plus the admin access is not password protected, it's just there. So any virus can probably bypass it.

In the Linux kernel different rings are isolated. So ring 0 is the kernel, and all outer rings have well designated privileges for each security layer.

So you know for use that the user privilege is just that, and any malware in this space can't normally interact with the root system.

Normally, because there is always some kind of kernel bug that creates privilege escalation. But it's less and less, the Debian team is working hard to patch all bugs, I support them 100%.

I think Open source is the future.
