For anyone looking to access the "deep web" a couple install tips that might make the difference between "oh sorry officer" and X years in jail.
DO NOT DOWNLOAD TO YOUR ROOT/C: DRIVE
Best course is to use true crypt, make a hidden volume, put embarrassing or confidential data in the outer volume (so you have a plausible reason to have the encrypted file),
Install virtual box to this drive, NOT TO C:, boot up a virtual windows, install true crypt on your VM, again with the hidden volume, install TOR inside the hidden volume, run TOR,
TURN OFF JAVASCRIPT,
when your done scrub your computer with a secure cleaner, like ccleaner, and poof, you can now do a lot more than you could before.
If your dead set on doing seriously illegal stuff, then you'll need to do a lot lot more, but there is no way in hell I'm telling you how.
