FIX YOUR FUCKING SEC
YOUR PHYSICAL SEC
This will be a novel, if you are impatient here is what you will do. Buy a spare/burner laptop, 2x usb drives, install GNU/Linux (Devuan/AntiX) toit. If wifi does not work, purchase a Linux Compatible wifi usb to plug into it. Follow the installer, watch videos on how to install one or the other with FULL DISK ENCRYPTION. And then use Tor to talk to your internet nazi frens.
If you can't get a second computer, just install Tails to a usb and only talk to your internet frens through that.
Operating Systems, you have a lot of choices, none of them are Windows 7, 8, 10, 95, ME, XP, or OSX, or Android/ChromeOS. Your choices are BSDs, GNU/Linux Distros of varying types, research OSes for supernerds, and things that are beyond brainlets. Here is a list of recommended Operating Systems
In all of your choices you want these two things, FDE (Full Disk Encryption), and no systemd.
OpenBSD - Secure by DEFAULT, there are some functional losses of operation, but it is the most secuire Operating System out there, VeraCrypt support is iffy (come back and check this). Tor-Browser is one pkg_add torbrowser in the command line away, and other useful tools for security. Install XFCE or Mate for a desktop environment from the command line and you're solid. Ethernet is required for people who can't into command line wifi. FDE offers keydisk option for advanced users.
Devuan - Debian without systemd, braindead simple to install and run things on. Everyone makes things for Ubuntu/Debian, almost everything that runs on them, will run on this.
AntiX - Debian, without systemd, run by leftists, but is a very good project.

Void - Advanced users only, high performance, BSDlike GNU/Linux distro, no systemd.
Artix - Arch without systemd, advanced configuration required for FDE, but still doable.
Gentoo - Advanced users only, sakaki guide recommended for hardened gentoo.
Sakaki Install Guide
Whonix - Secure by design, runs in a VM. The Whonix wiki is a great resource. Only inculded for people who cannot into anything else. SystemD is not an issue because it can be virtualized in a secure system.
Whonix Wiki - Recommended Reading
Alpine - Advanced users only, performance based Linux designed for servers, useful for virtual machines and webaspps. Not really a desktop system although it can be. FDE is for advanced users only, no systemd.
Slackware - Advanced users only, fde is difficult to accomplish, but can be done, a truly patrician choice.
Sourcemage - Advanced nerd users only.
Browser - Torbrowser, Iridium, Ungoogled Chromium, Hardened-DePozzed Firefucks, Palemoon
Chat - IRC(with gpg plugin), Mumble, Element/Riot
Additional Important Software - tor, torsocks, macchanger, virtualbox or qemu/kvm, gpgp, openvpn
Desktop Environment/GUI/Shell - XFCE, Cinnamon, Mate, LXQT, LXDE(for weak computers)
Simple - Use a pre-sandybridge Intel Processor or an AMD processor for computer. Or, use a Raspberry PI with sufficient power(RPI 4, 4gb of RAM)
Complex - Use a non x86 processor(advanced), use a librebooted x86 Processor(Advanced).
IBM/Lenovo Thinkpad, Dell Latitude, Panasonic Toughbook, GETAC, HP Elitebooks.
Everything before this was primarily software you should be using, now it is time to explain things you should and should not use. Some verbiage.
Telemetry - The thing that tells Amazon you're looking to buy shoes or a video game. It is packets of information made in the background of your computer, without you knowing that can give away who you are, or where you are.
Mirror - A webpage you download utility software from
PGP - Pretty Good Privacy, this is used to authenticate information, and encrypt information so that people can not read the contents of a conversation. GPG is the GNU implementation of it.
