I stay away from banks as much as possible.
If you were worried about someone gaining physical access to your computer and gathering your banking information from it, I'd advise encrypting your system, disabling cookies and javascript and enforcing https, and do not store usernames and/or passwords in whatever browser you choose to use. These are more just deterrents, as with physical access and enough time to a computer, they will get in eventually if they have the know how. But you might as well make it as difficult as possible for them. You could also look into luksnuke, and/or putting your boot partition on a removeable usb, for greater security, though I'm not sure if both these options can work in tandem.
If you're worried about someone breaking into your system remotely, I'd advise running Tor, which makes you harder to track, comes with HTTPS Everywhere, and No Script by default, and also follow above mentioned tips. There are many ways to enhance your security.
What I might advise is running an encrypted virtual machine of whatever distro you like with Whonix, inside your already encrypted sytem. There is a youtube tutorial of how to set this up with Kali. Just search Kali Whonix. And google Whonix as well so you know what it is.
Good luck
