Password protected items

In these cases, BitDefender is simply notifying you that it was unable to scan certain password-protected or otherwise encrypted items, due to the fact that a password or encryption key is required to access the contents of the archives/files that are listed. In order to scan these files with BitDefender, you will need to unlock these archives/files with the password that was used to protect them, or otherwise decrypt them using Windows Explorer, or another proprietary decryption method.

Regardless of this notification, BitDefender's real time protection will still block access to any infected file that may attempt to run on your computer and take the necessary actions to disinfect/quarantine the file.
