Do not save anything on your computer unless you encrypt it. If you want to keep stuff on your computer download trucrypt and create an encrypted partition on your hard drive with an outer and hidden inner partition. Then if you are 'forced' to give up a password you can give up the password to the outer volume, you need to make sure you save some innocuous stuff in the outer when you create it though, adding files later can corrupt the hidden inner partition. I run TOR from a USB that I never leave in my house, I also run an encrypted linux window for extra security that needs to be mounted via trucrypt. ENCRYPTION IS YOUR FRIEND!! LEARN ABOUT IT!!!
