I am getting the following message pop up on my Mac running Catalina.
"(null)" is an app downloaded from the internet. Are you sure you want to open it.
This file was downloaded from the internet on an unknown date.
Where do I find this file?
Thank you,

If it is an app it should be found in your Applications folder.
I would have thought so, but can't find anything there.
Malware scans OK - both Drive Genius and Malwarebytes.
Search doesn't find anything.
I don't know what it is either. I suggest you download the Malwarebytes app and run it. It is safe and will remove any malware you might have. You could also do a search for "null" and see if anything comes up. Last, you could download and run EtreCheckProIt will provide a system report of what is going on. Then post the report below on the paperclip. Some very competent people here can then review the report and offer some suggestions. Good luck.
