Thanks for your comment Ṣmeed.
I agree to a certain extend, that all those measures these articles offer as possible solution combined, might prevent a computer and it's software to be altered by unwanted intrusion. I do have some experience with measuring up to that but as it happens, there is the day when all that was not good enough.
Although privacy is a major concern to me and security a top level issue as well, all efforts to keep everything save and running are stall mate as soon as any update is installed or new software comes along. To constantly keep in mind what's at stake when it comes to those two issues is a drag and a manufactured one on top of that.
So it works out to be a deal between those two and certainly not to my full satisfaction.
Currently I have installed uMatrix and Adblock Plus on all browsers, two common addons that are supposed to deliver. Besides that I have to trust Google's and Microsoft's policies, when it comes to their preventive measures offering bits and bytes with backdoors as big as gates. Apparently even they have problems with that, as those articles you suggested make out.
So what can I do in a case of harm done already? Right now I switched to Chrome in order to get things done. That as a fact shouldn't sit well with mods of a Microsoft help forum.
