I am checking out the other links concerning tests to run. I'm pretty sure my 
hard disk is not corrupted; I run fsck fairly often. And I doubt it is 
bitcoin mining (although I only know bitcoin from the defensive position). 

I not only block (or attempt to block) bitcoin miners, but also modify my

Richard Stallman keeps telling me that the proper word here is "cracked" 
not "hacked"; and I agree, though I know everybody, including myself, says 
hacked for both good and bad. Anyway, if I have been cracked or hacked, it is 
either through brute force, or somebody got physical access to my computer 
(which I lock down when I leave the house); or maybe by somebody with a lot 
of money and resources. 

Otherwise, my attacker has impressive skills, and his/her/their talents are 
wasted on low-hanging fruit like whatever is on my computer. They really 
ought to consider aiming for bigger targets, as I will just crawl back under
