Step 1: Quit dubious process in Activity Monitor.

Activity Monitor shows all the applications and processes running at the time. If MainSearchSignal is active, there's a chance of finding the processes relevant to it by viewing Activity Monitor. You can follow the steps below to quit the MainSearchSignal-related processes:

4. Select a suspicious process, and click the cross icon at the top to quit it.
5. Click Force Quit. 

Step 2: Remove suspicious applications from the Applications folder.

Remembring we mentioned before that MainSearchSignal is usually distributed by another app? If you recall recently installing any application from the web that may be the carrier, you should uninstall it from the Applications folder.

Since MainSearchSignal may be installed as a separate app or cause the installation of other unwanted programs on your Mac, also take a look at the apps installed without you noticing.

1. Open Finder > Applications.
2. Right-click on the app you recently installed and choose Move to Trash. 
3. Inspect the apps, then trash those you suspect to be the culprits.
4. Empty the Trash.

Step 3: Trash files related to MainSearchSignal.

Malware or adware like MainSearchSignal needs to employ Launch Agent scripts for at least one stage of its attack. In the process, it generates files in several folders to help perform certain tasks. Cleaning these files is also essential to remove MainSearchSignal from your Mac. 

How to get rid of MainSearchSignal by deleting its related files:

1. Open Finder, then click Go > Go to Folder from the top menu bar.
2. Type in /Library/LaunchAgents and hit Enter to get to the folder. 
3. Check the list of files for suspicious ones, and those that look close to MainSearchSignal. (Some examples are "myppes.download.plist", "installmac.AppRemoval.plist", "kuklorest.update.plist", "mykotlerino.ltvbit.plist.")
4. Right-click on a file and select "Move to Trash."
5. Repeat from step 2 with the following folders that MainSearchSignal may leave a trace at:       ~/Library/LaunchAgents      /Library/Application Support       /Library/LaunchDaemons

Step 4: Delete MainSearchSignal in Profiles.

Another thing you should do to eliminate MainSearchSignal on Mac is to delete the profiles it creates. You can do that in System Preferences, but note that you won't see the Profiles system preference pane if no profiles are installed.

How to get rid of MainSearchSignal on Mac:

1. Go to the Apple logo > System Preferences > Profiles.
2. Select any dubious profile and click the ( - ) button to remove it. 
3. Empty the Trash.

Step 5: Uninstall malicious extensions from your browser.

Threats like MainSearchSignal often add malicious extensions or plug-ins to your browser and make unwanted changes to the settings. If you experience forced browser redirection and many pop-up ads, you need to put an end to these advertisements by uninstalling these programs and correcting your browser settings. Here, we will demonstrate how to do it with Safari, Google Chrome, and Firefox.

How to remove MainSearchSignal from Safari:

1. Launch Safari.
2. Click Safari > Preferences from the top-left menu bar.
3. Select the General tab and ensure the Homepage address is Safari's default start-up page or your chosen one. 
4. Choose the Extensions tab and look for extensions that are installed without your consent.
5. Select it and click Uninstall.

How to remove MainSearchSignal from Google Chrome:

Chrome has a reset feature that disables extensions and restores settings to the default while keeping information such as bookmarks, history, and passwords untouched. You can use this feature first, then uninstall rouge extensions.

1. Open Google Chrome.
2. Click the three dots at the top-right corner and select Settings.
3. Choose "Reset Settings" > "Restore settings to their original defaults."
4. Click "Reset Settings" to confirm your action. 
5. Tap on Extensions, and remove the extensions that look unfamiliar to you.

How to remove MainSearchSignal from Firefox:

Firefox also allows you to reset it to the factory state without losing bookmarks, history, passwords, cookies, etc. But it removes extensions saved to the Firefox profile folder. Therefore, you need to re-add the extensions you often use after refreshing Firefox and check the Extensions again since MainSearchSignal may not be stored in the profile folder.

1. Launch Firefox.
2. Click the three horizontal lines(menu button) at the top-right.
3. Select Help > More Troubleshooting Information.
4. Click "Refresh Firefox" twice.
5. Tap on Finish.
6. Click the menu button and select "Add-ons and themes."
7. Click Extensions and uninstall suspicious extensions not stored inside the Firefox profile folder.

Step 6: Employ a reliable anti-malware application.

If you have gone through the steps mentioned above, MainSearchSignal should be gone now. In case you want to double-check, you can download the free version of Malwarebytes for Mac, which can scan and remove adware from your Mac.
