I'll break your post up into fragments, and answer each in turn.

Spyware .. i presume this still applies to linux, although i suspect it may "effect" in less serious ways.. what about removal?
The only type of spyware you'll find in Linux as of this writing are simple browser cookies, just like in any Internet-capable OS. Configure your browser, e.g. Firefox, to flush cookies every time you quite the browser. No more cookies!

Firewall - Software whats a good firewall to use?
IPTables, included in any reputable distro. You just have to turn it on in most, which is usually a simple process.

Updates? - where do you get them from? (suse)
If you're using Suse Linux, you'd get your updates from Suse. Red Hat from Red Hat, etc. Each Linux distribution has its own method of handling updates, some of which are better/easier than others, but all work. It's actually much easier to keep your system up to date with a Linux system, since Linux updates all of the installed software on the machine. Not just central OS files, making for a more wholly secure system. In other words, not just your browser and networking tools are getting patched/updated, but your sound, graphics-editing software, etc. also!

And can someone possibly give me some information on linux.. how its designed e.t.c
I'm not sure exactly what you're asking, could you be more specific? I can tell you though that Linux is a free, Unix-like operating system which is built with stability, security, multiple-users and networking in mind. All devices on a system are represented as directories, i.e. /dev/cdrom, instead of an alphabetic designation, i.e. D:\. Also, just about everything can be customized and tuned to the user's preference in a Linux system, where you have a lot more flexibility in many ways than a proprietary system, such as MS Windows. If you have a more specific question along this line, feel free to pose it.

can you run linux.. and windows at the same time on one computer? (not dual boot) as in both at the same time.. ie for example: "windows emulating in linux" (most understanding way i can describe it)
Well, the short answer is "you really don't want to, trust me", especially the 'Linux running in Windows' part. If you want to run one in the other, it should be Windows running in Linux, for stability, security and resource reasons. This can be accomplished with software like
Win4Lin. However, it is much more prudent to either multi-boot (install both OSes, but seperately), or just run Linux and emulate necessary Windows software in Linux using WINE (for office-type stuff), or Cedega (for games), or some combination of both. To me, I run Linux exclusively (no Windows at all), and I run a few Windows-only games in Cedega. But for me, anything I can run in emulation is just icing on the cake, as I'm not dependant on any Windows software. Quite the contrary; there's a lot of network administration stuff which I can
only do in Linux, or at least some form of *nix. So if anything I'm dependant on Linux...
