Piriform Ltd Files

These are the Piriform Ltd files I've gathered, thanks to the FreeFixer users.

The FreeFixer tool treats files from Piriform Ltd as safe, which means that the Piriform Ltd 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 Piriform Ltd file(s). My guess is that those detections are incorrect and that the files are safe. It is unlikely that Piriform Ltd would ship a malware file.
