I am a Python / C developer currently working on a extremely important piece of software. The details of the code will not be mentioned, and the only place the code appears is on my own hard drive, in a virtual disk image used by a windows 7 virtual box (a hard drive inside a hard drive I guess). The algorithm represented in the code is extremely important, and I cant have ANYBODY get to it except me. I was curious if one could completely protect a single virtual folder from any unwanted access whatsoever. I want to give a level of protection so deep (for this one folder) that even if a CIA agent was assigned to tracking down this source code on my hard drive, they could not do it. I need this folder to be completely cut off from the rest of the world, and make sure no internet based attack, nor any virus could get to it. Is this possible? Any suggestions to lead me in the right direction?
P.S. As you can probably tell, I really don't know much about security, but I would appreciate any suggestions. A 'no this is not possible' answer is completely acceptable.
