Johnnyloans I'm pretty sure they watch my screen and listen to my phone calls. It's hard to know how they do it because I dont have the knowledge.
Though on my computer they left signs like wiping my logs in /var/log and leaving scripts in my /bin folder like one named pastebin, i looked at it and it was some kind of python script that looked like it put stuff on a paste site. One time my hosts file was pointing to a random ip, which was really weird.
Xorg bounces to the top of htop frequently, I find it doesnt do that as much when I manage to wipe the system clean. But they seem to be infecting my usbs because dd will show the progress then freeze after a certain point and my live usbs act like they have malware by showing errors all the time. To counter the live usb thing I bought myself a dvd r drive and bought myself a dvd for my os because that's read only so they cant infect that so I'll always have a copy to use that's clean. Just when I ordered it, I ordered it from a place thats taking a long time to send it to me.
