Microsoft AutoUpdate Mac virus removal [Aug 2019]

Mac malware is booming, with various adware and rogue antispyware strains steadily gearing up for a rise. A particularly deleterious vector of attacks, though, spans phishing and other forms of social engineering that target users’ credentials and personal data. On top of that, cybercriminals are constantly refining their tactics and trying their hand at highly persuasive methods to get hold of this valuable information. One of these hoaxes has seen a dramatic spike lately. It involves the “Required Data Notice” popup alerts mimicking ones from the legit Microsoft AutoUpdate. This service is intended to facilitate the way updates of Microsoft’s products are rolled out to Macs. Its benign essence is a major red herring in the new info-stealing campaign, where perpetrators deposit a malicious program onto macOS systems that keeps triggering the copycat popup dialogs. The infection is referred to as the Microsoft AutoUpdate Mac virus.

Microsoft AutoUpdate Mac virus in action

The purpose of the authentic Microsoft AutoUpdate notifications under scrutiny is to let the users know about a change in the company’s policy regarding the avenues of obtaining and handling diagnostic information related to their software, such as Office, Skype and the like. The alert emphasizes that these new practices won’t affect confidential details about the user or other products running on the Mac. All in all, this is a commonplace notice familiarizing the customers with certain tweaks. Once a person clicks OK, the message shouldn’t appear anymore. However, lots of Mac users have been complaining about persistent nature of the popups. They don’t vanish after the terms acceptance, plus the affected machines start running hot due to high processor load whenever the screens appear. This is merely one of the discrepancy reported by the victims.

There is one more red flag making people doubt the safe origin of these entities. In some cases, the users are redirected to a suspicious website that requests PII (personally identifiable information) under the guise of Microsoft. Among other things, the details include first and last name, credit card stuff, email, and Mac admin password. Obviously, Microsoft would never gather these details in such a manner. The entirety of adverse effects caused by these popups come down to the activity of the Microsoft AutoUpdate Mac virus. It is a stealthy application that usually comes bundled with harmless free software so that the users aren’t alerted. When on board, the parasite runs a series of commands to display the fake “Required Data Notice” message recurrently. This popup is linked to a phishing web page that tries to swindle personal information out of the victims.

The skyrocketing CPU usage could be caused by a furtive cryptocurrency mining script affiliated with the malware, although this is more of a speculation at this point. Perhaps the Microsoft AutoUpdate virus leads to a peculiar glitch in the host Mac, making the system allocate too many resources to some regular task. One way or another, this interference needs to be terminated before the consequences grow beyond a controllable point. Follow the steps below to address the issue.
