I have five computers. Two run Windows 7 and 8, respectively, in order to access certain programs that only work on Windows. The other three run Linux. I love Linux, and I'll tell you why. It's easy, for one thing. Over the years, Linux distributions have gotten smarter and made more of their operating system GUI, which means the times a user needs to drop to the command line to type anything in are few and far between. It's free. That matters in a world where Microsoft charges $100 a pop for an OS install. The spyware situation is a lot better than in Windows 10, too. Linux is not designed from the ground up to spy on its users, unlike Windows 10, which notifies Microsoft anytime you do something on your computer. Finally, Linux will run on anything. That old computer that ran Window XP until Windows XP finally died? It will run Linux fine. No problem. All the software we know and love--Firefox, Chrome, LibreOffice, qbittorrent, and SMplayer--are all on Linux.
I recommend keeping one or two Windows boxes around just to access those occasional Windows-only applications. There's seldom a good excuse to make an application Windows-only nowadays, because software languages can compile for many operating systems, including Mac, Linux, and PC, but some developers just don't get it or don't want to spend any extra effort toward supporting operating systems used by a small subset. Qbittorrent is an excellent torrenting program that runs on all three operating systems. Torrenting, by the way, is how we download Linux. The Linux distributors deliver their work to you via fast, efficient torrents to ensure a valid download and minimize consumption of web server resources.
Why do people bother making Linux distributions (distros)? Much of the motive I think centers around enthusiasm for knowledge, but having a Linux distro on one's resume certainly will lead to job offers, if one is in the market for one of the great-paying Linux jobs in corporate America. A large chunk of the Internet runs on Linux, incidentally, so Linux isn't going anywhere except continuing to improve, and will be around several generations from now.
One area where Linux has low adoption rates is the desktop/laptop market. Probably 1% of desktop users use Linux. This is mainly due to lack of awareness of what Linux is and what it offers and scarcity of knowledge resources. If your family uses Windows, then more than likely, you are going to go straight to Windows and not think twice about it. Microsoft has been great at marketing, and it does make a fairly good operating system, as well. I like Windows and use it. I just believe that Linux is a valid option that should be considered, especially by people who have been or may be victimized by malware.
The one thing about Linux that people don't know about is that Linux is secure. Your operating system is not going to go to hell because you clicked on a web site. It is not impossible, but it just does not happen, and why? Partly because the bad guys don't see a margin in targetting a 1% minority with generally higher levels of tech knowledge. Also, Linux is designed for security from the ground up. Goal number one was security. For Microsoft, goal number one was pleasing the business customer and making things as easy as possible all the time. Different philosophies, both laudable, but those who know less about computers ironically have a horrible experience with Windows once their computers become infected, which over time, they will.
Firefox is my favorite browser, when I don't have to use Internet Explorer or Chrome in order to access a specific web site for work-related reasons. I like Firefox because I like their philosophy, emphasizing security and efficiency. I do not know what Internet Explorer emphasizes. I trust Mozilla, the makers of Firefox, and I also like their mail reader, Thunderbird, another seldom-used and seldom-appreciated gem out there that makes reading email a lot safer and faster. Why people use a web browser to read their email, I do not know. It seems like a lot of trouble to me.
No-Script is my favorite add-on for Firefox, because it gives control back to the user as to what a web site can and cannot do. I can surf the worst malware site on the planet and yawn. Because the malware site cannot touch me. No-Script blocks everything they try to do. The most a malware site can do is annoy me with their tackiness. Meanwhile, the sites I love and trust, like gayauthors, work fine, and I let them do whatever they want. No-Script is a bouncer. You train it for a couple days, and it keeps the troublemakers out of your bar.
My advice to the desktop or laptop computer user is simple. I've said it before and I will say it again. Install a distro of Linux, any distro, and if you don't like it for some reason, fine, install another one. I am partial to Xubuntu and Linux Mint XFCE, but there are hundreds of distros to pick from, each with different philosophies and styles. Next, use Firefox as your browser. Install No-Script as an add-on within Firefox. Open your mind and learn as much as you can about Linux, Firefox, and NoScript, the golden triad of secure computing. From that point on, malware is something you do not worry about. You are more secure than 99.9% of all computer users out there. Period. It is as easy that.
