I have heard suggestions here to have an offline computer where keys are stored. Even transactions that need to be paid can be saved, entered into the offline computer, signed, and the confirmation transferred back to the flashdrive to be uploaded to the internet. But this requires a flashdrive to go back and forth. So how much does that compromise security?
If one only transmits specific files back and forth to the flashdrive, is it safe? Or is it possible for a program to install itself unknowingly on the flashdrive while in the internet-connected computer?
If i remember right, and as far as i know there are programs that can install them self on your computer without you knowing it, i mean from flash-drive. But there could be something that a person could do to maximize protection of computer. First do not give flesh-drive to anyone and do not use it on computer that you are not sure it is safe to use, second have a good antivirus program, but even with that you can not be safe 100 percents.
