I went to a site to research Real Picture Postcard (RPPC) dates, a site I've used many times in the past, and as soon as I did, adobe launched, for no reason.
The last time adobe started for no reason, I suddenly had Trojan Cryptic.AM on my computer demanding money to fix problems that didn't exist. It also shut down my anti-virus software, and disabled my ability to download anything.
This time when it kicked off, I hit the blue power button on the computer. I didn't shut down gracefully - well a bit more gracefully than pulling the plug, maybe, but just a bit. I just turned it off.
I don't know what would have happened had I not turned it off, maybe nothing. But everything seems fine - malwarebytes ran, scans came back clean, nothing bad is happening. Good.
But still, I don't understand.
