You've been given good advice.
There are many good reasons to use a Linux distro just as there are reasons to use MS Windows.
I use both.
But for different purposes and different reasons.
I use a Live DVD of Tahrpup online and am posting using it now. MS has nothing comparable that boots from a CD, DVD or flash drive.
Linux is more resistant to malware than Windows. Windows having more desktops in use also is of a greater focus for malicious intrusion. Where ever you are reading or hearing Linux is more prone to malware than Windows, it's simply not true. Never has been.
That said, I quit on Windows , on line, for a different reason that's irrelevant to this conversation.
Toolman has nailed it.
And if you haven't noticed, many Linux users use it the way they want.
With MS, you use it mostly the way they want.
If you spend the time to learn about Linux and use the forums for operational questions, I think you'll find there is a lot less stress worrying about malware, upgrades and security updates that cause conflicts.
I did and I now spend considerably less time on the Internet worrying about my operating system.
So .....make a choice of what distro looks interesting, test drive it, if that doesn't work out, try another distro until you find one you can live with.
