Any computer can be accessed through NSA-level malware/spyware. My computer is air-gapped (not connected to the internet in any way) but I still lose files and even Windows functions because they can and do tamper with everyone, no matter. I've lost files as quick as I downloaded them and transferred them over using a flash drive, so the Evil Overlords have eventually found their way onto my system and are probably still here (as bots). I believe this is what Windows upgrades are for, and if you don't accept them, they sneak on and change things anyway, taking away functions or changing my settings behind my back so I lose things. No wonder they push AI. That's what it's for.  Renaming files might be enough to throw off their AI malware. It depends how far they're willing to take this. From my experiences they never make it obvious and work slowly, obviously automated. But if they wanted to purge all computers of a particular file, they probably could do it in an instant.  The freakiest part of all this is the fact that you don't know how much access they really have, whether or not you're connected to the internet. The architecture could have full physical access hardwired into it and only the manufacturers and their Deep State partners would know. 1984 is definitely here.
