In Bitdefender system scan, it can't scan the password-protected files. I don't see an option to remove those files.
Hello,
Password-protected files belong in most cases to legitimate software. They are protected with a randomly generated password by their developers to avoid reverse engineering for malicious purposes. This is not a password that you would set. Most commonly, these are:
• Files that belong to another security solution.
• Files that belong to the operating system.
The password-protected archives require a password so that they can be opened and checked for malware. This notification appears because Bitdefender (or any other security solution) is unable to unpack the contents of such items and scan them. To actually scan their content, these files would need to either be extracted or otherwise decrypted.
When the notification pops up, you can:
• Type the password in the corresponding field so that Bitdefender can scan it (obviously if you know the password, if this is an item that was previously encrypted by you).
• Skip the object from that particular scan.
• Skip all password-protected items without scanning them.
Regardless of this, should the contents of the password-protected files be extracted, malware cannot attack from there because Bitdefender’s real-time protection would automatically scan them to keep your computer protected. If you want to scan this type of file you’ll have to contact the product manufacturer to provide you with more details on those files.Bitdefender's recommendation is to ignore password-protected archives as they are not infected and are not a threat to your system.
