I was surfing the forum and found a link to another web that show me a software called Protect Exe 0.4 beta. I still need to check for license, but most of the software in that page is open source so I think it's not a problem...
This program encrypt and password protect exe files... yes, I know is not "the best solution" but I think is something to help protect our PApps.
i.e. block firefox.exe with a password and then nobody can access our bookmarks and stored passwords so easy... I know it just need to copy our profiles, but that is not simple to figure out by regular people (like my secretary and other sneakers around here... lol)...
Also need to check for portability because it looks like it uses some kind of registry...
I'm thinking in protecting something like PAM or PStart exes, then when somebody double-click on my PDrive icon or it just try to run it it will run autorun.inf that's going to ask for a password (because it's just calling to a protected exe) and then... "dude! I can't use your PDrive, duh!"
Yeah, just explore the Pdrive, but must people just press enter on the window asking what to do...
Security trough obscurity is how JTH called it...
EDIT: I protected an exe on my PDrive inserted ni a Desktop runing WinXP, then went to my Laptop runing WinVista Home Premium... Norton detected as a trojan and deleted it automatically, I wasn't able to test it... But on the desktop, spyware terminator and NOD32 specifically run on the file didn't detected anything... ...I'll try again...
EDIT 2: I just updated clamwin portable and tested the file... nothing detected, so it's probably another fake from Norton...
