When you insert a pendrive into USB slot, the behavior or action you will achieve really depends on the current operating system of that computer; not anything inside the pendrive. So, technically, I don't think it is possible.

But, since Windows provides AutoRun mechanism, this is logically possible, but not a common/effective practice. Users can bypass AutoRun anytime, so nothing are protected with password. If you want to protect your files inside, you can use file archivers such as 7-zip or WinRAR to compress and encrypt the files with password.

There is a special file called AutoRun.ini which runs automatically whenever some external device is getting in touch with the op sys.

This will let you to execute a special program which might ensure that the drive is not accessible.

But in most of the cases, Antiviruses does not allow (or even ask the user) to give permission to run the program in Autorun.

So this would not be possible to ensure that those programs will run, as most of the viruses are created to transmit using Autorun.ini.

Rather than doing this, I think it is better to have a special application an exe which helps to unlock an encrypted folder inside your pen drive.
