My Context is always "Global" or some other I've chosen.
In the last (few days) I've checked some .nb posted online (some posted as viewable whole notebook - such as that coronovirus post)
I CHECKED MY CONTEXT and it was "CloudObjectPrivate" which it "should never be" as I do not use Wolfram cloud ever, not once, intentionally. I'm quite content using my local copy and
below is a list of what is in this Context. It looks to me like some notebook has or is trying to heist my kernel, and perhaps root my computer through / by the Mathematica kernel.
Does that look familiar to anyone?
I could see that being in "System`" but have no idea why it would be in cloud.
(again, my kernels are always local, i set my context by hand every kernel restart, it simply isn't possible that "i did it")
I SUSPECT A .NB POSTED ONLINE (viewable online) or a .nb i downloaded switched my Context to connect to foreign computers whereas i do not wish that - furthermore - there seems to be a "whole system under this foreign cloud object"
