Linux does not have viruses (Viri?). Other advantages are that most Linux distros (Distributions/flavours) will be considerably less resource intensive, a lot smaller than Windows,and run better (faster and much less 'crashy' - I've never had Linux crash the way Windows quite often does. Also, updates are always under your control, most Distros notify you of updates (Ubuntu and Mint are very good at this) and you can choose when to install them. As a family, we're completely Linux/open source. You'll find Linux is not at all scary or hard to use. most desktops follow the Win7 format. If you're new to Linux, I'd suggest starting with Mint and running it from a USB stick. There are lots of tutorials on making a bootable Linux USB stick from within Windows on YuTube, and elsewhere. Google is your friend.
