Hey guys its real simple to bank online first you download this iso then you burn it to a disc then you put it in your computer and make sure the bios is set to boot from cd... then you can bank online easy peasy using an new operating system.
Then when you have to actually do something with things you are used to just reboot and take out the cd until you have to bank again.
I doubt the majority of people with malware on their windows machine get past burning an iso to cd (unless they have windows 7 which has native iso burning technology).
