I read the article on the link you posted, and the conclusion is that only Microsoft can make a good security solution and that the Windows Defender only thing we need. But at the same time, Microsoft Windows 10 is one big spy machine that collects a huge amount of data and sends it for analysis.
Windows 10
is a privacy nightmare, though there are steps you can take to prevent that. It has a built in
keylogger, and even amidst large improvements on Microsoft's end, users are finding that they're
still collecting data. These may all be inconsequential at the end of the day considering Microsoft's reputation, but some people are still understandably concerned. I actually only use Windows for games and Linux for everything else (not because I don't trust Microsoft, Linux is just easier to secure), but I realize that that may be too big a leap for most people.
This may also be a good opportunity to remind people to
review their privacy settings.
Malwarebytes Premium version is not free, and a free version does not have any protection, it is only for scan&remove.
Yeah I only use the free version on my Windows machine, and come to think of it, I've never actually needed it lol. I've found that Windows Defender is good enough protection, and I only really have Malwarebytes for added insurance. To each his own though.
