Downloaded SCAM Office - (HOW TO SEARCH FOR FILES DOWNLOADED FROM INTERNET)

I downloaded what I thought was a legit Microsoft Office package for Mac, it took an appropriate amount of time to download (5-6 minutes), with the following installer:

Microsoft_365_and_Office_16.86.24060916_BusinessPro_Installer.pkg

Then received information from the SCAM company that I needed to download the following validator:

Microsoft_Office_2024_Validator.pkg

After the validator finished loading, there was no key to be found and no access to Microsoft Suite.

I researched the company AGM Software and learned the hard way that they have been scamming people for a long time. There is no way to contact them for support, LiveChat is a dead link and their reply email was listed as a warning in my spam filter.

I do not care about the money I lost. I learned the hard way.

I want to know how to find out what was loaded onto my MacBook Pro, and where I can find it so I can protect my sensitive data on my machine.

Thank you in advance.

I am not very tech-savvy so I appreciate any guidance from the community.
