The threat actors who masterminded the Mac Auto Fixer malware campaign apparently have some strong cybercriminal background and decent coding skills. Here is what proves this unsettling assumption. The application itself appears to be competently designed and gives you the delusive impression that it’s worth a shot to keep a Mac running smooth. Meanwhile, it obviously inherits multiple hallmarks of a rogue optimization tools lineage also represented by such an oldie as Advanced Mac Cleaner and newer impostors like Mac Mechanic and Mac Tonic, the former having dominated the Mac scareware landscape for many months on end. Furthermore, the baddie under scrutiny is backed by a massive distribution wave that rookies wouldn’t conduct. So we are undoubtedly confronted with a serious adversary spreading a well-tailored toxic program.

Mac Auto Fixer user interface is eye-catching, yet misleading for the most part

The despicable gist of Mac Auto Fixer comes down to inundating the host system with false positives in an attempt to pressure the victim into purchasing its license. This tactic is at least a decade old, but this particular rogueware implements it more persuasively than competitors. While imitating the detection of most issues it reports, the pest mixes them up with some actual minor system performance bugs to give you the big picture of an awfully unhealthy Mac that needs urgent repairing. To add insult to injury, the infection’s brainwashing logic isn’t restricted to deceptive scans running at random. It additionally displays frustrating popup errors reminding the victim that the more they linger with the fix the worse their machine’s stability status will get.

Mac Auto Fixer claims to detect numerous system issues

An extra intimidation technique that makes Mac Auto Fixer stand out from the crowd is that it also claims to deliver security features, not only performance-related ones. By falsely reporting a few Trojans or spyware entities, the counterfeit cleaner further increases the odds of duping the user into coughing up some money for the “fully-functional” edition. The preys who are obsessed with privacy might also get on the hook after seeing a report with a bunch tracking cookies and other privacy issues allegedly spotted on board the Mac. Overall, Mac Auto Fixer seems to have all sensitive areas covered in its manipulative routine, therefore sober thinking and rejecting its crafty recommendations are the tips of the day for those infected.

One more nuisance precipitated by the surreptitious installation of Mac Auto Fixer is that the web browsers slip out of the victim’s control. The scareware adds an extension that replaces the original preferences in Safari, Chrome, and Firefox with set-ups that make the user frown. The goal of this tampering is to make the person recurrently head to a web page crammed up with popup alerts or to a website designed for accepting payments for the app’s license. This adds a layer of pressure on top of the fake system scans and warning messages generated by the pseudo system utility itself.

Maftask, the core process triggered by Mac Auto Fixer virus

An extra symptom of this attack is that a process named maftask can be pinpointed in the infected Mac’s Activity Monitor. This is the underlying malicious executable that coerces the system to behave in a particular way. In many scenarios, the victims don’t even have to explore the running processes to discover this entity. Since macOS Catalina release, Macs have been giving users a heads up about installed suspicious applications through popup alerts. In the case of Mac Auto Fixer, these dialogs say, “maftask will damage your computer. You should move it to the Trash”. Although these warnings have a “Move to Bin” button, clicking on it doesn’t remove the virus because it’s more stubborn than the average Mac threat. Its persistence, in part, comes down to a shady device profile created without the user’s awareness and permission.

Mac Auto Fixer also poses a privacy risk that shouldn’t be underestimated. It quietly collects information that may allow its operators to profile the victim uniquely and haunt them with phishing hoaxes and targeted ads down the road. This data includes, among other things, the IP address, macOS version, hardware specifications, running apps, and web surfing history. When mishandled by a competent malicious third party, these details can have serious negative implications for the user.

Although this rogue program isn’t really progressive in terms of distribution methods and relies on the good-ol’ bundling trickery, it boasts well-orchestrated propagation that results in thousands of Mac users being infected daily. As unsuspecting users are installing some freeware via custom setup clients, Mac Auto Fixer tailgates inside their systems alongside the primary installs. So the next time you decide to get a free applet from a site with unknown or dubious reputation, be sure to check what’s under the hood of the setup wizard by opting out of the default installation option. Then, simply deselect whatever you deem redundant. Anyway, Mac Auto Fixer is malicious and should be removed from Mac immediately. The walkthroughs below will lend you a helping hand with the cleanup.

Mac Auto Fixer virus manual removal for Mac

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

  1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.

    Go to Utilities

  2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.

    Select the Activity Monitor

  3. In the Activity Monitor app, look for maftask or another process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.

    Stop malicious process

  4. When a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit option.

    Select the Force Quit option

  5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.

    Use the Go to Folder feature

  6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.

    Open /Library/LaunchAgents folder

  7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

    As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.techyutil.maftask.plist, com.techyutil.mafuninstaller.plist, com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

    Root-level LaunchAgents folder contents

  8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).

    Open ~/Library/Application Support folder

  9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are Mac Auto Fixer, ProgressSite, and IdeaShared.

    Application Support folder contents

  10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.

    Open ~/Library/LaunchAgents directory

  11. The system will display LaunchAgents residing in the current user’s Home directory. Look for dodgy items related to Mac Auto Fixer virus (see logic highlighted in subsections above) and drag the suspects to the Trash.

    Contents of LaunchAgents folder in user’s home directory

  12. Type /Library/LaunchDaemons in the Go to Folder search field.

    Go to /Library/LaunchDaemons

  13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.techyutil.maftask.plistcom.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.

    LaunchDaemons folder contents

  14. Click on the Go menu icon in your Mac’s Finder and select Applications on the list.

    Go to Applications screen on Mac

  15. Find the entry for Mac Auto Fixer or another app that clearly doesn’t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.

    Drag malicious app to the Trash

  16. Expand the Apple menu and select System Preferences.

    Select System Preferences

    Open System Preferences

  17. Proceed to Users & Groups and click on the Login Items tab.

    Proceed to Users & Groups

    The system will display the list of items launched when the computer is starting up. Locate the potentially unwanted app there and click on the “-” (minus) button.

    Delete unwanted login item

  18. Now select Profiles under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.

    Select Profiles under System Preferences

No, Mac Mechanic has nothing to do with Apple. It isn’t a regular performance enhancement tool either. Just like Mac Auto Fixer thoroughly analyzed in the above tutorial, it is an imitation maintenance tool that tries to dupe users into buying its licensed version. In fact, both applications hail from the same source and take a very similar unethical route in terms of the tactics.

Originally discovered in 2018, Mac Mechanic tailgates into computers alongside benign-looking or junk programs advertised on low-quality software download repositories. Once on board a system, it spoofs an unsatisfactory condition of the host by displaying counterfeit scan results that list dozens or hundreds of memory hogs, redundant cache files, unused language packages, and logs. Most of these items aren’t even there, so the high improvement potential signaled by these scan reports is a fake. Therefore, every user who discovers this Mac Mechanic would be better off uninstalling it without hesitation.

Nspchlpr is the name of a malicious process associated with Similar Photo Cleaner, an application originating from the same scareware pool as Mac Auto Fixer, Mac Mechanic, and Mac Tonic. The program in question isn’t legit or trustworthy because it intentionally deluges a user’s computing experience with faux notifications about gigabytes of disk space that can be supposedly released by trashing duplicate images.

Some victims become alerted to the presence of Nspchlpr process on their Macs in a straightforward way. The recent tweaks in macOS mechanisms for flagging suspicious code result in periodic popups that go, “nspchlpr will damage your computer. You should move it to the Bin”. Whereas this is a real system warning, it quickly becomes intolerable because Similar Photo Cleaner cannot be removed via a classic uninstall technique and the dialogs continue to appear incessantly.

If Mac Auto Fixer has cropped up on your Mac, you’ll have to think of the box to make it vanish. It is a stubborn threat by design and therefore the removal isn’t only a matter of going to Applications and dragging its icon to the Trash. In an attempt to thwart a victim’s uninstalling efforts, it creates multiple LaunchAgents, LaunchDaemons, and folders in the Application Support path. Additionally Mac Auto Fixer mishandles the login items feature and the device profiles functionality to run at boot time and maintain control of web browsing preferences on the machine.

To get rid of it for good, the related files and folders should be removed from all the affected system areas. Plus, it’s necessary to revert to the correct web browsing settings. Please follow the steps listed in the Mac Auto Fixer removal guide above to spot and delete every fragment of this malicious app and undo the unwanted changes it made.
