The technology race is generally a favorable concept that calls forth progress at the end of the day. If different service providers didn’t have to compete with one another, there would be less motivation for them to excel in their industries and create top-notch products better than someone else’s. This permanent state of contest doesn’t mean war, though. The interaction between Apple and Microsoft is a good example. One of the areas where the corporations’ activities overlap is their proprietary products. Lots of Mac fans use Microsoft Office, OneDrive, Skype and other solutions every single day. There are versions of these suites that support macOS, which is a perfectly understandable move by the Redmond-based tech giant that tries to expand its audience. Is everything going smooth in this regard? Not really. The recent influx of negative feedback over what’s called the Microsoft AutoUpdate Mac virus has really been the talk of the town since at least mid-July 2019. In fact, this issue was first brought up years ago, but it seems to have reached a critical threshold this month.

Normally, the Microsoft AutoUpdate tool runs silently in the background and performs its routine job to make sure the person uses the latest builds of MS products. It streamlines the way the appropriate updates are rolled out and installed on Mac machines, with the goal being to make the software fine-tuning process hassle-free and seamless. The problem that’s currently affecting Mac users on a large scale has to do with popups supposedly generated by this trustworthy service. In particular, these alerts may read “Required Data Notice”. The contents of this notification seem to be aligned with the recent release of a new AutoUpdate variant for Macs. It is known to request optional diagnostic data so that the vendor can improve the way its applications operate in the macOS environment. Some people might dislike this tactic, but it’s nothing new for major companies. There could be a much more serious caveat in this whole story, though.

The dark side of this matter boils down to cybercriminals’ involvement with this controversial data collection initiative. The alerts mentioned above could stem from the shenanigans of the Microsoft AutoUpdate Mac virus. It is a piece of malicious code that triggers the popup dialogs impersonating Microsoft’s legit service. There is a fundamental difference between the objectives and the impact in the two scenarios. If it’s malware that causes these warning messages to appear, then the goal is to forward the unsuspecting Mac users to a phishing page that asks for sensitive information, including their name, address, and credit card details. Notice that Microsoft is collecting purely technical diagnostic data, nothing more than that. The malefactors simply mimic the genuine popup request to take advantage of the actual software maker’s reputation and thereby instill trust in the victims to perform identity theft.

Another side effect of the crooks’ pranks is the abnormal CPU consumption that accompanies the alerts. The Mac may slow down to a crawl or even freeze and reboot. Lots of victims have been reporting the Required Data Notice popup waking up their MacBook laptops even when the lid is closed, which is absolutely unacceptable for a regular interaction scenario between a service provider and a user. To top it off, the affected machine’s fan gets very noisy as it starts running at maximum speed to cool down the hardware. The quirk may last for hours if the glitch occurs, say, at night. Clicking the OK button actually dismisses the notification in most cases and saves the processing unit from permanently maxing out its resources, but the same thing tends to happen again after a while. This may entail a hardware failure in the long run. Furthermore, the quandary doesn’t seem to make sense to numerous affected users because they have no Microsoft products installed on their Macs in the first place. All of this havoc is definitely subject to immediate troubleshooting. Below is a step-by-step guide to completely remove the Microsoft AutoUpdate virus from Mac.

FAQ

The accurate answer depends on whether you are dealing with the legit or malware-riddled variant of the updater suite. If it’s the former scenario, then you should browse to “/Library/Application Support/Microsoft” on your Mac. A handy way of doing this is to use the “Go to Folder” feature and type or paste the above path in the search box. When the directory is opened, find a folder with “MAU” string in its name – for instance, MAU2.0. Once you expand it, you will see the executable named “Microsoft AutoUpdate.app”. If you are sure you don’t need it anymore, go ahead and drag this file to the Trash. Empty the Trash folder when done.

On a side note, this operation is worth performing if the MAU application is giving you a hard time with its random popups accompanied by overly high CPU consumption. Another situation where the removal makes sense is if the Microsoft product you used to keep on your Mac (such as Office 365, Project, or Visio) has been uninstalled but the AutoUpdate tool hasn’t been deleted for some reason and keeps running regardless.

In the event the irritating notifications are splashing up because of malware activity, the file path and removal logic tend to be different. To get rid of the culprit, follow the steps provided in this article (see the guide above). In a nutshell, you should additionally examine the Applications folder and the Login Items to spot the traces of the unwelcome entity. Note that its name may suggest no obvious association with MAU (Microsoft AutoUpdate).

Microsoft Update Site

Not necessarily. It could be a legitimate element of a Microsoft software suite you have been using. Also, chances are it’s a leftover component of different versions of Office 365, Project, or Visio solution that hasn’t been automatically eradicated as part of the removal of the underlying software. And yes, the valid edition of Microsoft AutoUpdate might cause issues outlined in this tutorial – due to a glitch or some other misconfiguration predicament.

Update Microsoft

The malicious counterpart of MAU may try to defraud Mac users of their sensitive data under the guise of the genuine app. The symptoms can be similar, except that the “Learn More” or “OK” button leads to a phishing page rather than the appropriate Microsoft knowledge base. If this is the case, a security procedure aimed at thorough Mac cleanup is strongly recommended.
