So what I'm going to do to secure my computers and device until I get better with computers

1. Remove the backdoors in my hardware
2. Fresh install of a OS without backdoors
3. Lock the system files and some other directory like my documents. Only the programs I have choose can access them.
4. Never give the root to anything
5. Use a firewall with a prompt for each programs that try to connect to the internet with the whole globe blocked beside the one I try to reach
6. Use a powerful top priority task manager
7. My subroot is on my mouse, the full root is locked and cannot be unlock and if I get some friends the root can be access only with MY keyboard.
8. Play

Now I guess, that I'll need a good tech to do that. And maybe someday, with the programs, I'll be able to do that all by myself.
