Does anyone know an EASY way to encrypt an application and data files on a Windows machine? This is a machine that will be used by staff, and I don't want them having access to Thunderbird, FileZilla etc... I also want to encrypt the data files that these applications use (Thunderbird inbox, FileZilla FTP ini file etc...). I do NOT want to encrypt the entire drive. I've had a quick look at WinGuard, but haven't tried it yet. Any suggestions?
