Etrecheck – System Information

Malwarebytes can be useful. There are no viruses in the wild for macOS, but there is malware... adware, trojans, etc. Those are not viruses, but use social engineering and trickery to get you to install them. If you use common sense, you shouldn't really have to worry about those.

Unfortunately, if you google virtually any windows or mac executable or process name, you're going to come up with a web site that will try to convince you it's a virus and push their worse than garbage cleaning software to get rid of it. It's just the nature of the internet these days...

Let it run for a while and see if it settles down. Not knowing exactly what your situation is (recent upgrade, etc.) It's hard to say exactly what it's working on, but it's not malicious.

It is reported to be a virus. See if you can remove it with Malwarebytes.

It's not a virus. There are no viruses in the wild that can affect macOS.

This is related to photos. Either uploading or downloading photos from iCloud or importing and indexing a photo library.

I can't confirm it is a virus, but I will vouch for Malwarebytes. It was written by Thomas R, a long time poster. It and Etrecheck are the 2 most recommended programs for troubleshooting.

I did a Google search which you can also do if you think I did not provide correct information. I have no idea what your problem with MalwareBytes is.

You are welcome.
