How to circumvent a false positive "infected file"

Today, for some reason, Bitdefender decided that the Windows diagnostic tool LicensingDiag.ps1 is infected:

The file \\OF-Pub-NAS1\Public\Product Downloads\Windows Diagnostic Tools\LicensingDiag.ps1 is infected with Heur.BZC.PZQ.Boxter.989.A320B4FE. Bitdefender blocked this item, your device is safe.

It's possible that this file was recently infected, but it's Date Modified flag is 6/1/2018. As far as I know I've never used this ****** and don't need it now, but I would like to at least look at it but I don't have permission. I assume Bitdefender modified the file permissions in order to "protect" me. Yes? If so, how do I check the validity of this file?
