The following are the Adobe Systems Incorporated files I have gathered, thanks to the FreeFixer users.
The FreeFixer tool treats files from Adobe Systems Incorporated as trusted, which means that the Adobe Systems Incorporated 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 Adobe Systems Incorporated file(s). My guess is that those detections are false positives and that the files are safe. It's unlikely that Adobe Systems Incorporated would ship a malware file.
