These are the Microsoft Windows Component Publisher files I've collected, thanks to the FreeFixer users.
The FreeFixer tool treats files from Microsoft Windows Component Publisher as safe, which means that the Microsoft Windows Component Publisher files will appear with a green background and that there's no removal checkbox for the file. However, as you can see in the scan results below, a few of the anti-virus scanners detects the Microsoft Windows Component Publisher file(s). My guess is that those detections are incorrect and that the files are safe. It is unlikely that Microsoft Windows Component Publisher would ship a malware file.
