I don't recommend it, I personally haven't done this but people I have talk to that run ubuntu in windows say's that a lot of windows crappy security features will have a massive effect on ubuntu. Get a disc and completely get rid of windows.
If you want you can go to ubuntu.com and request a free disc of ubuntu 10.04. They usually send with no questions asked but it can take some time to get there.
You can run a virtual machines of Linux with in windows
Security feature like against viruses? There are no viruses out there for linux. Or are you talking about people hacking into your computer? It is extremely hard for people to be able to hack a through a Linux OS but if you want some firewall protection then go to applications>ubuntu software center. Then type in firewall in the search bar and use the one ubuntu provides, The software in the ubuntu software center is programs that are garunteed (by ubuntu) to work with your OS and makes install extremely easy, plus the fear of any viruses (none are known to exist) and hackers are go away due to the fact it is secure.
Finally remember that your OS interface for your desktop is 100% on you for how you make it look, you can leave it the way it is but you can also completely change how it looks and operates and it is easy to do.
I am sure there is some virus out there. They are more rare, but still existent.
EDIT- Also, make sure that your computer can boot from USB
From what I have been told on my Linux forums long ago (when using ubuntu hardy) that viruses are created by Linux users not for Linux users.
As far as I know I have not found a case of anyone claiming to have got a virus and it was legit. Sorry buddy. Plus even if there was some rare cases of it happening there would be some anti virus out there for us.

It can be done, but may not be. Either way, the OP doesn't need to worry about it.
That link is complete rubbish. First of all a virus is a self propagating program that payloads malicious code. Meaning it runs on it's own. There are zero known viruses in the wild for any *nix system.
I will give you proof of concept, malware, trojans and possible escalated code from things like web browsers. However, those are require user interaction of some sort and are not a virus. A virus acts on it's own.
Also that article you linked is from 1997 and gives zero information on that so-called virus. It was most likely a publicity stunt by McCaffee to sell more AV software.
OK, I give. I can't find another single article. And, I somehow missed the 1997 stamp on it.
LOL, so true. Windows is a virus magnet.You give up? Why was it so important for you to find a virus for Linux to begin with? Is it possible that MS Windows security sucks so bad that it is the only OS I know of that is popluar to get viruses (yes).
