There is a lot of room for argument over whether Linux is more secure in theory. But Linux is overwhelmingly more secure in practice.

A far smaller fraction of Linux systems are ever infected by malware than Windows systems.

In my own experience with Windows, the UAC system is not usable. Too many things simply don't work unless you completely disable UAC. Constantly logged in with admin rights and UAC disabled means you are running an insecure system. But logged in without admin rights and/or enabling UAC means you are running a broken system. I'm sure most people have simpler requirements for their Windows systems and can afford a higher level of security. But the difference with Linux is very clear. The same more complicated requirements in Linux are still no reason to make the system insecure.

I think most of the practical difference in security comes from two other effects, not from inherent security advantages of Linux:
1) Target size. The same level of effort finding and exploiting a security flaw will give a far higher payback in Windows because there is a larger pool of targets. So people writing malware focus their efforts on Windows, leaving Linux safer.
2) Competence of other users. Just as an unvaccinated person is safer from disease around vaccinated people than around other unvaccinated people, a computer with sloppy security practices is safer running a OS where the majority of users of the same OS have good security practices (Linux) than one where almost all users have sloppy security practices (Windows).

For average computer user the security question comes down to the malware / virus question. How easy it is to get infected on a Windows box vs Linux box. Of course there is massive amount of malware for Windows out there and next to none for theLinux. That however does not mean, that Windows is less secure. If you are not running as a admin user in Windows and hav UAC activated then any malware trying to do something with your system ends up with a prompt on your face. If you are not running as root in Linux then any malware trying to access sensitive parts of your system will simply fail.

Then again majority of Linux'es have one or more daemons running under root permissions and a true hacker wanting to get into your box would target those to crash them and get a root access by that means. No such thing in Windows I believe.

Malware trying to wipe out your home directory contents can easily do it both on Windows and Linux. There are countrless ways to get for example keyloggers into either Windows or Linux systems.

So which one is more secure, huh?

ok, I have a newbi question....

I'm now using Linux Mint and I'm using the default user you create when you start using it.
Is it root? When I open the terminal and I write "sudo su" it ask for a password and then the thing that was there change. So this mean I'm not a root user right?

Thanks! (: and this is really interesting, btw I just installed apparmor.

The default user of Ubuntu like systems (like Mint is) is not root. If you use the sudo command you are root only in that specific terminal.
