Yes, you could try Linux, especially, Ubuntu... Ubuntu is more akin to windows in terms of X-Window operations. And another thing is, Linux file system don't allow viruses to intrude into your system. If you need some tweaks, tips on optimizing your Linux Ubuntu system, visit my friend's website,
netstat -an | grep -i listen... I have tested all of his Linux system optimization using that site.
Have fun with your Linux experience as I do. IF you are confused or needs help aside from the Ubuntu Documentation, you can drop me a line here... I'm sure to help you, guys....
