How to get rid of Search Marquis?

Getting rid of "Search Marquis" is easy and you don't need to install anything.

To ascertain the cause so that you can eliminate it, start by inspecting the contents of the following folder:

~/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. Make sure all its file names are readable by selecting View > as List or other selection that shows that folder's complete contents. Then, take a screenshot of that Finder window.

• To learn how to capture a screenshot please read the Appendix in the following User Tip: Writing an effective Apple Support Communities question. It also includes instructions for posting a screenshot in a reply to this Discussion, so keep that Safari window open for now.

Often, there is nothing in that Launch Agents folder so don't be surprised to find it empty.

In the same manner as the above, navigate to this next folder:

/Library/LaunchDaemons

The Finder's Go menu > Go to Folder... field should look like this:

... and click the Go button once again.

Once again ensure all its files and their names are readable and capture a screenshot.

Then, repeat that exercise with the following folder:

/Library/LaunchAgents

Notice its pathname is different than the other two. The Finder's Go menu > Go to Folder... field should look like this:

In the end, you will have captured the contents of the following three separate folders:

~/Library/LaunchAgents

/Library/LaunchDaemons

/Library/LaunchAgents

All three will be saved to your Mac's Desktop with names "Screen Shot... " followed by the date and time they were captured. Please be sure to include or otherwise indicate the name of the folder that corresponds to each screenshot, so that you and I can keep track of which ones they are.

Post the entire contents of all three windows, one at a time, using the "picture" icon that appears below your reply text:

You already did the hard part by navigating to those folders and posting their contents. The rest is easy.

First, ensure you have a reliable backup of your Mac, in case something should go wrong with continued troubleshooting. To learn how to do that, please read Back up your Mac with Time Machine.

• A backup is a fundamental prerequisite regardless of whatever method you may choose uninstall adware, and would apply even if your Mac were running perfectly well. Do not overlook this fundamental requirement. It's important.

Next: This step will prevent the scam products from loading so that they can be removed while they are inactive. Restart in "Safe Mode", and log in: How to use safe mode on your Mac. Starting in Safe Mode takes longer than usual so let it finish. The rogue processes affecting that Mac are inoperative in "Safe Mode".

The following files and / or folders need to be deleted while using your Mac in "Safe Mode":

Second screenshot:

Drag that selection of files to the Trash. You may be asked to authenticate. Confirm they are no longer present in that folder. Leave all the others alone, but read my comments regarding "CleanMyMac" later.

Nothing needs to be deleted from the folders in your other two screenshots.

Next: open Safari and select the Safari menu > Preferences... > Extensions. If you see any Safari Extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone. No Safari Extensions are required for normal operation. Then, select the General pane and review your Homepage selection. Repeat those equivalent actions for any other browser you may use (Brave, Firefox, or Opera for example).

There may also be adware-associated app icons in your Mac's Applications folder. Open it and examine its contents. Any unwanted or mysterious app icons should be obvious to you, but again please don't remove anything if you are uncertain—ask first. Identify any suspicious apps by name, or post another screenshot.

Next: In an abundance of caution, examine System Preferences > Extensions. Determine if there are any System Extensions that may have been installed without your knowledge. Ask if you're uncertain.

Remaining in System Preferences, check for the presence of any Profiles. Profiles are installed by organizations with a need to manage Macs deployed in institutional corporate or educational environments (for example), but have also been exploited by adware creators and similar malcontents. If any Profiles are installed on your Mac an icon like this will appear in System Preferences:

If you see that icon in System Preferences, select it. To remove a Profile, select it, then click the [—] (minus) button and authenticate.

Remaining in System Preferences, open Users & Groups. Select your User Account's Login Items. You may or may not find those Applications in its list. If you do, select them then click the [—] (minus) button to remove them from Login Items.

You can then restart your Mac and log in as usual. Evaluate its operation and ensure everything is working as you expect it should.

Next: if you want to eradicate all remaining adware remnants post a screenshot of the following folder, in the same manner as you did earlier:

~/Library/Application Support

It is normal for that folder to contain many items, but anything associated with the above adware may contain identical names. If you find a folder or folders bearing those names, drag those folders to the Trash. Without the files you already removed or the reintroduction of similar malware, they can do nothing but occupy space. These can be removed if you wish, but again don't remove anything if you are uncertain.

Next: It appears that Mac has been affected by a non-Apple "cleaning" product. Those things are destructive in nature and should never be installed on any Mac. Remove "CleanMyMac" according to its instructions. In extreme cases, erasing the affected Mac and reconfiguring it from the ground up is the only practicable way to recover from the effects of having used it, or products like it.

Finally: If any of the above actions result in abnormal operation or if something else stops working, the easiest way to recover would be to restore the Time Machine backup you created as a prerequisite, so the importance of that fundamental step cannot be overemphasized.

First screenshot:

Drag that selection of files to the Trash. You may be asked to authenticate. Confirm they are no longer present in that folder. Leave all the others alone for now.

Note: The two ZipCloud files may or may not be related to the problem. However, the fact they have been associated with malware in the past is beyond dispute. Unless you use that product and are certain you need it, those two files should be removed for that reason. Without exception, non-Apple "cloud backup" products are inferior to Time Machine, and if they are "free" they should be especially regarded as suspect.

Nothing needs to be deleted from the folders in your other two screenshots.

Drag that selection of files to the Trash. You may be asked to authenticate. Confirm they are no longer present in that folder. Leave all the others alone for now, but please read my comments regarding "CleanMyMac" and the two "NanoResults" files later.

Note: The two "NanoResults" files may or may not be related to the problem. The reason for my suspicion is that I am unaware of any Mac program that goes by that name. If you are absolutely certain you are using a program by that name, then leave them in place.

Nothing needs to be deleted from the folder in your second screenshot.

Next: open Safari and select the Safari menu > Preferences... > Extensions.

Next: Like all non-Apple "cleaning" products, "CleanMyMac" is junk. It cannot be determined from your three screenshots whether it remains active or not, but Rule 1 of Macs is don't install junk. If you installed it at one time and subsequently uninstalled it according to its instructions and your Mac is otherwise working properly, then all is good. Following those instructions may have left that one "CleanMyMac3.Scheduler" .plist file behind. It's ok to remove it too.
