This can be nice option, but it will run much slowly. The other problem is Ubuntu CD is static point of software that was released some moths ago (Ubuntu releases every 6 months - no revolution needed like on Windows XP --> Windows Vista, just minor updates). Ubuntu is designed to update itself and whole software installed on the system only by using one click! Because today modern software is made of billions of programming code it is impossible to be 100% free of security bugs. So it gets updates and you should install updates - it is easy to do this, because window pops-up and ask if you would like to install updates. So updating the system is what makes you secure. Live CD was secure when it was released, but new security problems could be known and already fixed.
One more difference between Windows and Ubuntu. On Windows you download some exe file from internet and install the program, you get wizard and you install it. Then you have lets say at least 50 small programs on computer like office suite, cd burning tool, music player etc but do you update this programs every day, because they can have some security problems in it and fix is already released but you haven't installed it, so you are at risk. On Ubuntu there is centralized software repository. What ever you install (just using one click, no wizards at all) from repository Ubuntu knows it and checks daily if there is some update available and if it is it installs it. So what makes Ubuntu vs. Windows security is regular updates. You know on Windows you can have some fix available for months or years, but if you didn't install the fix you can get security problems. How does security attacks works: Microsoft and other companies publish on there web sites that there is security vulnerability and fix is available to install. But hackers read this instructions and makes programs to exploit it. The real problem is that users don't install fixes. On Ubuntu all software is updated from central repository, so you can't miss some security update.

No, Windows programs (and Windows viruses) can't be run if Ubuntu is turned on. But unplug Ubuntu USB Drive when you are finished.

Download it from official site

This is one of the biggest difference on Linux environment that you will not see on Windows. Every "dam" think you can imagine you have 100 options to choose from. You have Ubuntu (GNOME environment - very simple to use), Kubuntu (KDE environment - more advance desktop environment for users that want to set 100 and 100 settings), Edubuntu (for schools, education), Mythbuntu (specialized for music & video etc), Xubuntu (for older PCs) etc etc etc. This all of the options goes on with all software you can imagine like text editor: gedit, kate, vim, etc etc etc. There are tons of other Linux distributions like Fedora (new software as possible), OpenSuse, ArchLinux (for computer geeks), Gentoo (for extra computer geeks), etc etc etc. There is no "single" solution on Linux and that is great, but also "big" trouble for beginner. But you know to solve this problem there was Ubuntu, which was designed for average user who doesn't like to decide between 100 programs and 100 settings and 100 other stuff, but instead all of the software that is needed for average user is installed, configured and ready for use out of the box. You will get one program for each purpose: Firefox browser, Gedit text editor, Emphaty chat program (supports MSN chat, Google chat, any chat you imagine), Nautilus file manager (very very similar to Windows Explorer), Totem Movie Player (one click music player) etc. All packed for one purpose: just start using it. Don't bother with install, configure etc. just use it.
What I suggest you is don't be confused by all of this tons of options you can have. It is just like you were in supermarket tons of products to choose from, but you have your favorite chocolate and this favorite chocolate is called Ubuntu. Download it, install it, love it. All other tons of millions of options you can have later if you would like to have them or have a need for having them, both of which I sincerity doubt, because Ubuntu is what average user will ever need.
