WinZip Computing Files

The following are the WinZip Computing files I've collected, thanks to the FreeFixer users.

The FreeFixer tool treats files from WinZip Computing as safe, which means that the WinZip Computing 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 WinZip Computing file(s). I'm pretty sure those detections are false positives and that the files are safe. It's unlikely that WinZip Computing would ship a malware file.

Scanner and Detection Names

Here's the detection names for the WinZip Computing files. I have grouped the detection names by each scanner engine. Thanks to VirusTotal for the scan results.

As mentioned above, I think these detections are false positives since it is very unlikely that WinZip Computing would ship a malware file.
