I called the computer repair company today and got good news and bad news.
The good news is the hard drive is likely okay.
The bad news is the mother board has is likely about to die.
Which means either a new computer, something we haven’t budgeted for, or reversion to the old computer I got from my company, probably manufactured in 1999.
So maybe it wasn’t the trojan horses, viruses, and worms that killed it.
