Microsoft Dynamic Code Publisher Files

The FreeFixer tool treats files from Microsoft Dynamic Code Publisher as trusted, which means that the Microsoft Dynamic Code Publisher files will appear with a green background and that there is 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 Dynamic Code Publisher file(s). My guess is that those detections are incorrect and that the files are safe. It's unlikely that Microsoft Dynamic Code Publisher would ship a malware file.
