For Windows Defender, you can look for the detection entry and choose to allow it. Or, just temporarily turn off real-time protection.

For example though, in the registry at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Exclusions\Paths", there's a dword set to 0 with the name of C:\Users\myusername\Downloads\operapassview\OperaPassView.exe that was created when I added the exe to the exclusions list in Defender's settings. But, I had no problem downloading it in the first place as real-time protection was off.

@rif I guess the nature of the program itself is the reason for the security programs to complain about it.

I've used this 5+ times over the years with no problems ever downloading it.
