Password "protected" files in ProgramData folder

I just installed Bitdefender in my computer. During the first scan it detected a large number of files that are password protected as far as Bitdefender is concerned. I am wondering if these files are indeed password protected and so what is the reason for it.

They are mainly in C:\ProgramData\Topaz Labs LLC\Topaz Sharpen AI\tgrc and the other folders for Gigapixel & DeNoise. Some of them have a .tz extension.

Thank you.
