I have been hacked

That Mac has been maliciously tampered with. That's a crime. Stop using it.

I looked at the EtreCheck report briefly. Congratulations on managing your computer well. While this issue is clearly over my head, I can offer some observations. If this were me, here is what I wold do.

• I would open About This Mac under the Apple logo.
• I would click on System Report.
• I would then click on Applications. Be patient, it takes a while to display.
• You will see displayed a lot of apps. Ignore the Apple apps. Check the complete list of non Apple apps and write them all down which you aren't familiar with. There may be several.
• Then go to the internet to confirm that they are all valid apps.
• If you see something in question, I would seriously consider removing it. All of it. I would (and do) use AppCleaner. It is safe and very easy to remove. It can remove all aspects of any app.
• What I would be looking for is a app that enables someone to come in and control the computer. There may be some other way to do it, but I don;'t know about such things.
• If you later find you made a mistake, then you can always reinstall the removed app.
• Beyond this, work with your bank to enable security, etc.

Good luck to you in dealing with this.

I have another thought. If someone was able to download an app which enables them to take control of your computer, it must have been because you previously visited a web site and then did a download of something that was corrupted. Think back on where it might have been. Second, you might do an internet search on methods used to remotely control a Mac without having first granted permission.
