Yep. I have a smart TV I keep dumbed down. I KNOW someone (from the darknet or the CCP) is in this Windows PC right now. I have not booted it up for nine months in Windows since I discovered it last December. As a defense I keep only a set amount in my primary account, and I've lowered my daily limits for both withdrawals and ATM direct cash withdrawals. I know they are in here right now. The most sophisticated of them can burrow so deep that they can read the characters of your Windows login itself.
For the last nine months, and when I first joined here, I used a Linux USB boot stick. I still do use it a lot. IMO every PC user should pre-build one so they can log in in the event of an emergency. You might have to enter your email account info each time you log in...and your screen preferences, if only to see what Linux thinks you are trying to do...etc. It was only mildly annoying, really. I quickly got used to it, and in fact, it was somewhat "freeing" NOT to have to scan email with each login. To set the screen size and resolution. Ok...I could deal with it. Maybe ten extra seconds each time.
