I would just dual boot windows with Linux. It seems windows is compromised at this point. I am not seeing or reading anything on the net that tells how to fix windows so it is not compromised. Something may come up in a few months, but no one seems to know what to do just yet.
I was going to delete it, but think I’ll hold-off on that. No telling how embedded and cross-linked a *.dll file is in the OS.
