Yeah, I've been using Windows PCs for practically my whole life and I have to say that a lot of their bad rep is greatly exaggerated by Apple marketing. I've never paid for antivirus protection, and especially since Windows 8, the free Windows Defender that comes installed offer sufficient protection so long as you're not visiting really sketchy parts of the web and downloading sketchy stuff. The best malware protection is common sense and keeping your OS up to date.
A lot of the bad rap that Windows has received is due to Windows itself and Microsoft's handling of Windows. Of course the usual apologetics come into play with placing blame on OEM drivers, OEM software, and so on.
Windows is fine for people who install little to no software beyond what comes preloaded on their systems. But for people who regularly install software, Windows will slowly but steadily slow down to a crawl over time. Typically when a new app is needed for a function, one might install 2, 3, or more alternatives to test to see which one suits the needs best. Once selected, the others are removed.
Windows still does not offer a system-level software management tool. As a result, many developers rolls their own (or use 3rd party tools to create installers/updaters/uninstallers) and the uninstaller leaves behind junk that can slow a system down. orphaned system services, auto-update checkers, etc.
I regularly perform system maintenance not only on my Windows systems, but on those of my non-techie friends and family. Usually when they're complaining about their system slowing down and thinking of buying a new one. After I'm done, they're amazed at how well it runs... often times better than when it was new because I remove/disable the bloatware. But not everybody is capable of doing that. THAT is in part, what contributes to the reputation that Windows has earned.
There are many who complain about their Windows systems that have never been exposed to Apple's marketing.
