I'm getting pop up message "helpermcp will damage your computer you should move it to bin. When. Doing it is again popping up .resulting. Unable to openany application this is happing once I have upgraded to Catalina today.ki.dly help.

Download EtreCheck and run it. After it scans your Mac it will probably be under Minor Issues and will day there are things that may need attention. Click on it and find the one that says Helpermcp and delete. Restart computer and done!

OK open up your LaunchAgents file! This is where my problem was...I found out this folder is typically empty but I had 5 things in there and one of them was the culprit!!! Once I deleted the file with the same portion listed in the popup my problem was solved!!! Delete it, remove your trash and you must restart your computer. Hope this is helpful.

Navigate to the following folder, and post its contents in a screenshot:

~/Library/LaunchAgents

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. Make it look like this:

... and click the Go button.

A Finder window will open. Take a screenshot showing all that folder's contents, and post it in a reply. To learn how to do that please read the Appendix in the following User Tip: Writing an effective Apple Support Communities question.

Usually, there is nothing in that folder so don't be surprised to find it empty. The reason for starting with that folder is to eliminate other potential causes before proceeding with steps that will identify and eradicate whatever is affecting that Mac.

There will be additional instructions to follow and this is just the first step.

For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware.

Review your Gatekeeper settings. To learn about Gatekeeper read Safely open apps on your Mac. Gatekeeper is designed to help prevent you from inadvertently installing garbage software.

I used Spotlight to find the file and then trashed it. Afterwards Catalina identified two other files--one was Yem I think. I did the same thing. Then I went into the Library and searched for associated plists and trashed those as well. Alls well now.

/Library/LaunchAgents

/Library/LaunchDaemons

I do use Adobe quite a lot, so I don't think I should delete any of those. I did download Malwarebytes and did a scan. It deleted some threats that it found and I restarted my computer. It hasn't popped up since, so I guess it got rid of it. Thank you for your help though :)

My option was:

open Finder, enter “helpermcp” in the search item box, you will see two lines, in my case, highlight and drag to trash.

so far it has worked for me.

Mine was imbedded in my start up signatures. Once I deleted it there and restarted the computer I didn't have any more problems. IT was not an application but some residual stuff that was within my startup. I am trying to find the directions I followed to share....sorry I don't have them in front of me....

Received the same message regarding a different file. I was able to search the exact file name in finder as others mentioned and find the file and drag to trash, then empty trash. Very frustrating until lI found the solution!

This is a ridiculous thread. Most of us have lives. What kind of a consumer product demand this much of our time? If Apple were cheap, it would be one thing, but it’s really expensive, and they expect us to do this? Ridiculous. I’m done with them.

I'm getting pop up message helpermcp will damage your computer.you should move it to bin.when I'm doing it is reoccurring again and again. I'm not able to open any application on my Mac book air 2018.please help.this is after I have upgraded to Catalina today.

I am experiencing the same problem. A persistent pop up window keeps appearing stating "helpermcp will damage your computer. You should move it to the trash." It has rendered my Mac almost unusable and I'm very frustrated. Catalina is underwhelming thus far. Are you listening Apple?

Thank you for this. I was getting a similar message. followed your instructions and was able to fine the files that was causing this pop up and simply moved it to trash and deleted the trash...problem solved.

I'm having the same problem except mine says "guid" will damage your computer. you should move it to the trash. When I click move to the trash, nothing is in my trash bin, and it keeps popping up. I searched for guid in my finder but several things came up and I'm not sure which one I need to delete.

I just wanted to thank you for the guide to how to remove the pop ups. I followed it to the letter and it worked. Grateful thanks! The pop ups arrived soon as I'd downloaded the new update Catalina. Thanks again.
