If you are a regular Mac user, surely you have seen in more than one occasion a pop-up window with the following message when you browse the Internet or use some program: System Scan is Recommended: Click Start Scan to launch system diagnostics.
Your Spanish version will be something like this: Recommended system scanner: Click on the start button to start the system diagnosis. Saying pop up It can leave you even when you are convinced that your computer is not infected.
You may also have seen another similar window in which an Update Tracker is promoted. It is usual to think that it is about malware, but in reality the only thing that happens is that you have MacKeeper installed.
It's about a software somewhat complicated to uninstall that other apps, but for that we are here to explain how to do it. Keep reading to understand why you have it installed and to know the 5 steps to follow to get rid of the program.
On the other hand, and despite its bad reputation, we should not consider MacKeeper as malware. There are users who have even found it useful. However, there is no doubt that the way he has to sneak into people's Macs is nothing appropriate or respectable.
Why do you have MacKeeper installed on your computer?
It's hard to know why you have MacKeeper installed on your computer. In our case, for example, it happened after having installed three Android emulators for Mac more or less often: Andy, BlueStacks and VirtualBox.
We suspect that it was included in the installation package of one of these programs, although we do not know what. Maybe the culprit was the somewhat dubious web page from which we downloaded it and not the application itself.
Other users have blamed MacKeeper's presence on their system for downloading an apparently harmless Adobe update. It should really be an infected version of Acrobat Reader.
Step 1. Open MacKeeper from the Applications folder
Although it may sound counterproductive, the first step is to open MacKeeper because we must check something before uninstalling it forever. Surely you never opened it before, but you just have to go to the folder of Applications.
Once there, locate the file corresponding to MacKeeper and double click on the icon to open the program. Now, click on the drop-down menu and select the option called Preferences, which means Preferences in English.
If you have an old version installed, you will get a window with several sections. Touch on the tab general and deselect the option Show MacKeeper icon in menu bar so that the MacKeeper icon stops appearing in the top bar of your Mac.
On the other hand, if you have a more updated version installed, by clicking on Preferences, you will see a window with two unique tabs: Update Tracker and Account. Anyway, do not click on anything else and close the program.
Step 2. Delete MacKeeper files with AppCleaner
Now is the time to get rid of all the files you may have installed on your Mac related to MacKeeper. To do this, we recommend using the cleaner AppCleaner, which besides being free, is very effective.
Once you have downloaded this program on your computer, click it and drag the MacKeeper icon from the Applications folder to the AppCleaner. Then, confirm that you want me to delete all the files that you find related to MacKeeper.
We prefer to perform this step before uninstalling MacKeeper because, if we do it the other way around, it will not be so easy for us to tell AppCleaner what kind of files to look for and delete, so the results achieved will not be as good.
Step 3. Uninstall MacKeeper
Now that we have completed an initial file cleanup, it is time to remove MacKeeper. To do this, the first thing you should do is drag the icon of the program from the Applications folder to the paper bin. You may be asked for your password.
Once you have done this first step, if you have an old version, you will get a floating window in which you will be asked the reasons why you are removing the app. You do not have to answer the survey; you can simply click Uninstall MacKeeper.
Theoretically, when clicking on this button, both MacKeeper-related files and the application itself should be deleted. However, in most cases it is not possible to erase them all and that is why we have used the AppCleaner before.
On the other hand, if you were using a more updated version, you will automatically open the web browser that you have predetermined and you will be forced to select an option in the poll. You should not, instead, fill in all the boxes with information.
Once you're done, click on Next to go to the next page and finally hit Submit to terminate the process. In this case, it does not appear to delete any file other than that of the app itself.
Step 4. Make a final cleaning of the system
One of the last steps to follow is to make sure that there is no trace of the files that were installed on our computer with MacKeeper. Surely we will have already eliminated them with the previous steps, but it is worth checking.
First, visit the Library folder. To open it, open the Finder, select the tab Go from the top toolbar, followed by Go to the folder …. Enter the following command: ~/Library and press the button Go.
In the new folder, locate another folder called MacKeeper Helper. Once you've found it, drag it to the trash can and vacala to make sure it's well removed from your Mac.
As a protection mode, you can also check if there are any other MacKeeper related files using the following commands. Once you have deleted the files, go to the trash and restart your computer.
- ~/ Library / Application Support / MacKeeper Helper
Step 5. Get rid of the pop-ups from MacKeeper
The MacKeeper removal process cannot be terminated until you have also got rid of the annoying pop-ups that come out whenever you browse the web or use an app that requires an Internet connection.
You can be sure that they will continue there if you had a somewhat dubious version of MacKeeper instead of the one you can download from your official website. To remove these pop-ups, you just have to clean your browser.
The steps to follow will vary from one browser to another, but the idea is the same. You should clear the cache memory, clean the cookies and remove any extension that you don't remember installing and that you don't use at all.
If you use Chrome, go to Window and select Extensions from the menu Uninstall those of which you do not know the origin. Then, hit Chrome, followed by Clear browsing data and select the three options. Finally, click on Delete data.
On the other hand, if you use Safari, tap on preferences, followed by Extensions and delete those that you had not installed manually. Then, go to the tab of Privacy, Choose Website data and remove everything related to MacKeeper.
