Hi there,
Win10 is soon not supported. Tbh Linux have been on my radar since I started to break from the US big tech.
But how is security handled in Linux? Linux is pretty open-source, or am I not understanding it correctly. So how can I as a new user make sure to have the most secure machine as possible?
Shut the computer down. That’s it; computer as secure as possible.
Otherwise, if you actually want to use your computer, google for “threat model” first.
But generally: use an adblocker in your webbrowser, don’t execute random commands/tools from the internet before you know for sure what you’re doing, update stuff now and then and make backups.
