How do I get rid of windows 7 and switch to ubuntu?

You shouldn't run into any problem at all when you do that. When you run ubuntu off a CD or thumb drive you'll notice there's a little "install ubuntu" icon that's on the desktop. Just double click that when you're ready to install or choose the "install ubuntu permanently on hard disk" option from the menu you get when you boot your computer.

At some point early on in the installation process it will notice you have windows already installed and it will ask you if you want to wipe windows away completely and have nothing but ubuntu, or would you prefer to have both OS's share the hard drive in a dual-boot scenario. Since it sounds like you want to just be done with windows entirely, I guess you would choose the "wipe it away" option. If you're a more technically savvy person there's also a third option that will let you manually define the partitions and everything on the hard drive.

The Ubuntu installation is dead easy, about as easy as the windows installation. You won't have any trouble with it at all.

I admit, Windows is a terrific OS, with loads of 3rd party programs...and it's fairly easy to use.

The only problem with it is you can't go on the Internet and have any confidence about it's security.

Look into 'dual boot', and you can have the best of both worlds...just keep Windows off the 'Net.
