Type character malicious software

Next, download the EtreCheck app and run it. Post its report in a reply. It is likely to reveal additional files that need to be deleted.

For instructions, please refer to How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report - Apple Community.

First, start your Mac in "Safe Mode": How to use safe mode on your Mac - Apple Support. Starting in Safe Mode takes longer than usual so let it finish.

While in that mode, drag the following items to the Trash:

Then, restart your Mac normally and confirm the alert messages cease to appear.

Notes:

1. The "Malwarebytes" product appears to be installed, or was not completely uninstalled. You can see for yourself that it did nothing to address the "<app> will damage your computer" message. It's your decision whether to keep it installed or not, but no product can provide absolute protection from becoming deceived into willfully installing junk. Recognition and avoidance is the only effective defense. For more regarding that subject, read How to install adware - Apple Community.
2. Please be advised that non-Apple "drive manager" or "utility" products are never required on Macs. Using Western Digital "drive managers" and products like it have been known to cause spontaneous and unrecoverable disk erasure. The same recommendation applies to it.

DebStock apparently that Mac is suffering from a more extensive affliction than the "... damage your computer" message. The inability to do something as simple as opening a app downloaded from the Internet significantly hinders troubleshooting.

I wonder if the Western Digital "drive manager" product has anything to do with that, but this is wildly speculative.

Before we give up please try this one last suggestion: restart your Mac in "Safe Mode": Use safe mode on your Mac - Apple Support and determine if the EtreCheck app can be opened while in that mode.

However — and this is important — generating the EtreCheck report while running in Safe Mode will not reveal most if not all potential factors affecting that Mac. The objective for now is strictly limited to determining if you can even open the app.

Then, restart your Mac normally (not "Safe Mode") and try launching the EtreCheck app again.

Please write back with your results.

Hello - thank you for your help. I followed the clear and detailed instructions, moved the highlight files to the trash and emptied the trash. After rebooting, I am still getting the message (see attached). What else do you suggest. Kindly, Debbie

Am I to understand you downloaded the EtreCheckPro.zip file and opened it while in Safe Mode, but Terminal opened instead?

Obviously that's not supposed to happen. Not in normal mode, not in safe mode, not ever.

Given all these obstructions to progress, I doubt I can offer much more assistance to you in this particular thread. Please do me a favor and post a brand new question along those lines. When you do that, I suggest describing the inability to open the EtreCheck Pro app, so posting a question with that title will attract the attention you need. "Downloaded EtreCheck but I can't open it" might be a good title.

In that new question, describe that you tried downloading it several times but the initial screenshot appeared (the application can't be opened). Then you tried Safe Mode, and Terminal opened instead.

Something is going on that needs attention from a greater number of people, and posting a brand new question will elicit that interest. Click the Ask the Community link above. I will monitor that thread for replies, and provide any insight I might come up with between now and then.

After resolving that problem we can turn our attention back to the "... will damage your computer" message that brought you here to begin with.

I appreciate your continued help and interest. I will follow your advice and open a new thread in Ask the Community. Let's see if others have encountered this problem and found a solution.

To be clear, I was in normal mode, not safe mode.

I need help getting rid of type character malicious software. See the three screenshots below.

The EtreCheck app will not open. I've downloaded it twice. Any suggestions?

I changed my security settings on my Mac to allow for an not downloaded from the App store to be loaded on my computer. Once I did that I received the attached message from EtreCheck.
