I've used computers a bit less since 90s, and I'm also careful not to do dumb stuff on it. But I can't guarantee that any of any PCs at any time is virus free, because I don't know it and can't know it. And that includes Linux btw, though statistically it is much safer. But Linux is beside the point, the whole topic is about removing a Windows component, and on Windows there are millions of different malware.
