I have a windows 10 computer, I clicked on a link, it installed a Trojan file, they now can take remote access to my pc and are trying to purchase things on Amazon while I’m at work. How can I secure my pc without having to reset it? I have 2FA on my accounts now but still. I want to be able to leave my computer on at night and while I work without worrying what they will do. If my PC is off can they do anything?
