Microsoft Windows Publisher - 0.08% Detection Rate *

Did you just download a file that has a digital signature from Microsoft Windows Publisher and wonder if the file is safe? If that's the case, please read on.

You will probably see Microsoft Windows Publisher when clicking to run the file. The publisher name is then displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:

  2. Right-click on the file and select Properties
  3. Click on the Digital Signatures tab
  4. Click the View Certificate button

Microsoft Windows Publisher Files

These are the Microsoft Windows Publisher files I have gathered, thanks to the FreeFixer users.

The FreeFixer tool treats files from Microsoft Windows Publisher as trusted, which means that the Microsoft Windows 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 Publisher file(s). My guess is that those detections are false positives and that the files are safe. It's unlikely that Microsoft Windows Publisher would ship a malware file.
