How can I make a file in Xubuntu (or any ubuntu) indelible, or at least unreadable (if not undeleteable)? And is there a way to make this extend to Windows? I tried running the 'sudo chattr +i file.ext' command, but it did not work (the Terminal returned an error line).
The reason I ask this is that, one my computer (my Windows one), I extract Brutus from it's Zipped folder, but right after I place it in a folder, Windows XP immediately removes it. I have no idea why. I figured that maybe (since Unix has more editability) I could fix this issue on my Xubuntu box. It (being my Windows computer) also does it to other EXEs, not just Brutus (albeit certain ones).
