Understand that whatever can be hacked will be hacked.
Unplug everything from your computer when you are not using it. Disconnect from the Internet when you close down.
If you feel jumpy, immediately disconnect or put the computer on ‘airplane mode’.
What you have to understand is that it is not that hard for someone to hack into your computer.
If, for example, you are disconnected from the Internet while you are typing articles, than no one can hack into your computer.
It is like having a phone with no SIM card or battery. No one can call you.
You finish writing, you connect, you post, then disconnect.
Any hacker will find you too annoying to bother with and move on to someone else.
