Anti-virus programs can mistakenly identify a medicine or a treated file as a virus.
If you didn't find a file in the downloaded distribution, it means that your antivirus or Windows Defender ate it.
Before unzipping archive(-s) and using the medicine or the treated file, disable the protection of the antivirus and/or Windows Defender in real time.
In some cases, you may need to add a file and/or folder and/or process to the Windows Defender exceptions or your antivirus.
Here is the instructions:
