Actually, a couple of years ago, I bought some WiFi capable "smart plugs", from Amazon. After a couple of days, i had a problem, where something, repeatably, crashed, while I was in Firefox. After I investigated, it was a program. called Hello.exe. Looking further, that is, apparently, one of those ransomeware things. The, so called, smart plugs opened a path for the virus to be introduced into my computer. OS/2 just spit it out, with no damage. It did infect my router, but a reset to factory fixed that. Amazon did take them back, but nobody did anything else about it.
The "problem", today, is that perfectly valid software is classified as a "problem", simply because microsoft did not make a dollar, by "inspecting" the files.
