GAS INFORMATICA LTDA Files

The following are the GAS INFORMATICA LTDA files I have collected, thanks to the FreeFixer users.

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