well, in brazil you even have gbieh.dll - an undeletable, unkillable, always running, mysterious, "security" file/process from banco do brasil. http://www.file.net/process/gbieh.dll.html
Can't tell if trolling or not. That's an URL and they can name it with whatever name they want (.dll, 1761,1238,196.htm, .php, etc), and has absolutely nothing to do with an actual process running on your machine.
No so easy mate. Brazil has one of the largest bank concentration in the world, orchestraded of course by the central bank. We have the choice of 6 major banks, in this order of size -> Banco do Brasil, Itaú, Bradesco, BNDES, Caixa Econômica Federal, Santander
They are all highly regulated and with very little incentive to innovate. So they can screw around and do pretty much nothing at all. The fascist/socialist banking system that exists across the globe is even more pronounced here.
Pretty much every bank in Brazil optimizes for its largest target audience. Since most of their account holders run Windows and Internet Explorer and are able to install a Java runtime, that's what they will go for.
I have accounts on three banks that work well with Ubuntu and Firefox. Only one of them mandates a Java runtime to be installed (and only enforces the requirement on Windows and OSX).
that's even (slightly) worse than a java applet.
