No security is possible online.

Most people say to use Kali Linux, which is good advice but even it does not claim to be an actually secure operating system, since it has zero security/defense features, much less than most versions of Linux.

Qubes is also often touted as "reasonably secure" because it partitions everything into VMs, but what the creator (female) didn't realize, and the developers didn't have the heart to tell her, is that attackers are likely to exploit one of the numerous exploits constantly being discovered in the Xen hypervisor used by Qubes should they wish to attack a Qubes machine.

Other than the above and a few memes and scams it appears that no other OS is recommended for security, rendering the entire concept of "computer security" a scam akin to the medical industry where "cures" merely suppress symptoms momentarily.

But when I'm walking around I don't expect to have cameras placed on me that will record my pin at the ATM. On the internet this is exactly what happens except that it is your passwords not pin. Why do you think I use 2-fac on everything? Not for my health, buddy! And 2-fac isn't even uber-secure, many times I've been sim sniped and my 2-fac intercepted with a MITM play.
