Bazille's tutorial is excellent but I suspect it might frighten a few people off, especially those who may not be very tech savvy. Just setting up Whonix hosted on Virtual Box is actually very straightforward and does not require a huge amount of computer knowledge and know how. Obviously if you want a high level of security it is worth the time and effort to get your head around what is required and make it happen. If however you just want to step up your security to something a lot more robust than just using the Tor Browser Bundle you might want to consider Whonix by itself, check out their website (clearnet) https://www.whonix.org/wiki/Main_Page You can still save the VM's on encrypted media like an SD card or USB so that they are not saved on your machine.
