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?
Usually that’s called sandboxing. AUR packages do not have any, if you install random AUR packages without reading them, you run the risk of installing malware. Using Flatpaks from Flathub while keeping their permissions in check with a tool like Flatseal can help guard against this.
The main difference is that even with the AUR being completely user submitted content, they’re centralized repositories, unlike random websites. Malware on the AUR is significantly less common, though not impossible. Using packages that have a better reputation will avoid some malware, simply because other people have looked at the same package.
There is no good FOSS Linux antivirus (that also targets Linux). Clamav “is the closest”, though it won’t help much.
