From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

the most secure possible? you'll need to learn a ton. you'll get there, but it'll take a while.
decently secure? install Linux Mint, install your updates, don't run sketchy commands with URLs in them unless you know what you're doing, maybe follow a hardening guide. you'll be okay.
if you need to be extremely secure and private, install Tails on a USB stick. it will be slow and frustrating, and you'll need to save files to a second USB drive, but it will probably keep you pretty safe, and it's decently user-friendly. just make sure you keep Tails updated! you'll have to do that by flashing the new Tails onto a new USB drive, there's no easy way around that.
those are your two most user-friendly, safe approaches.
