Learn how to get rid of annoying “Your Mac is infected with 3 viruses” browser alerts and get best practice tips on dealing with tech support scams like that.

Update: October 2019

Cybercrime and social engineering go hand in hand these days. Targeting computer software alone tends to be much more difficult than exploiting human weaknesses, so to speak. Rather than focus on a single attack vector, though, some threat actors prefer combining the two. This is how tech support scams work. The fraudulent campaign to be analyzed herein revolves around bogus browser alerts saying, “Your Mac is infected with 3 viruses” or “Your system is infected with 3 viruses”. The message sure sounds scary, doesn’t it? Having stumbled upon it, some Mac users will end up following the malicious prompts provided on the page, and that’s a slippery slope.

Let’s delve into the technical nature of this online fraud. Obviously, Mac users do not go to the spoof web page in question because they want to. These forcible hits are facilitated by perpetrating scripts on hacked sites, or by malicious code previously deposited on the Mac. Some of the domains reportedly involved in this shady activity include apple.com-protect-systems-live, apple.com-supportcenter.pro, apple.com-traffic-cleaner.systems, and som008.site. The redirect begins with a popup warning that provides the following information, “Immediate action required. We have detected a Trojan virus (e.tre456_worm_osx) on your Mac. Press OK to begin the repair process.” The wording may vary, but the idea is to catch the user’s eye and persuade them to proceed. No matter what option is selected on the popup, the incursion moves on and the victim ends up on the main page that goes,

Your system is infected with 3 viruses!

Your Mac is infected with 3 viruses. Our security check found traces of 2 malware and 1 phishing/spyware. System damage: 28.1% - Immediate removal required!

The immediate removal of the viruses is required to prevent further system damage, loss of Apps, Photos or other files. Traces of 1 phishing /spyware were found on your Mac. Personal and banking information are at risk.

To avoid more damage click on ‘Scan Now’ immediately. Our deep scan will provide help immediately.”

The whole message is a complete fake. However, it is designed quite competently, includes the official logo of AppleCare Protection Plan, and generally looks trustworthy. The ‘Scan Now’ button in the bottom part of the page will download and install MacKeeper, a malware cleanup tool with controversial reputation. It gained notoriety for malvertising activity and false positives used to persuade Mac users to purchase its license. One of the most disconcerting things about the alerts in question is that the browser redirects may be triggered by a hijacker application that changes Internet surfing defaults on a compromised machine.

So, the main takeaway is to refrain from following the recommendations provided by “Your Mac is infected with 3 viruses” scam alerts. Another one is to check the system for browser redirect malware and remove it if detected.

FAQ

How To Check A Mac For Viruses

Apple might give users a heads up in certain cases. The Gatekeeper technology built into Macs is permanently on the lookout for malicious code you may unwittingly try to run on your computer. An example of how it works would be an alert about an application that exhibits clearly malicious behavior or underwent suspicious modifications since it was last verified. Another red flag that the system’s defenses easily identify is an unknown Developer ID.

In either scenario, macOS will generate a pop up dialog that lets you know about possible danger. It either emphasizes that you can execute the app at your own risk or strongly recommends moving the culprit to the Trash without allowing you to run it altogether.

However, Apple does not engage in alerting Mac users through pop ups isolated to a web browser. In other words, virus warnings you may see on websites don’t originate from the company, clearly stemming from malicious activity instead. Cybercriminals have refined their skills over time so that the pages hosting these notifications bear a close resemblance to Apple’s online resources and contain the company logo along with reassuring phrases such as “Apple Care Protection Plan”.

To recap, you should ignore online virus warnings pretending to emanate from Apple. A rule of thumb is to abstain from downloading any software off of these landing pages, otherwise your Mac might get badly infected with more viruses than just the browser hijacker that’s redirecting you to the faux web source in the first place.

Although skepticism regarding the efficiency of third-party security software for Macs is still quite a widespread phenomenon, this perspective has become somewhat dated over the past few years. The period of breaking new ground in terms of Mac malware distribution is history – nowadays Macs are being heavily targeted by cybercrooks and the system’s native protection mechanisms don’t appear to do the trick anymore.

You will probably get a security alert from the system when trying to launch a known-malicious application created by an unverified developer, but the Gatekeeper feature is unlikely to safeguard you if you’re up to executing competently obfuscated zero-day threat that comes in a bundle with benign software. With that said, there are AV labs that have had some notable success in spotting and removing Mac viruses.

How To Check Apple Mac For Virus

A few worthwhile tools in this niche include Combo Cleaner and Freshmac. Unlike the native Mac defenses that deliver real-time protection only, these utilities are equipped with on-demand scan features so that you can check your system for infections whenever you feel something isn’t right with the machine. So, getting back to the question: yes, you can scan your Mac for viruses. Moreover, you should do it regularly to be on the safe side these days

Let’s get something straight: pop ups are just the tip of the iceberg as there is always a virus strain that causes them to appear. Therefore, you cannot get rid of them unless you address the underlying security issue

. If the irksome pop up alerts or ads only occur in a web browser, it means your MacBook has a virus that installed a rogue browser plugin or extension without your awareness and consent. In this situation, the logic of the cleanup is as follows: eradicate the malicious app, disable the unwanted browser extension, and then revise your web surfing preferences.

Scareware can also be a source of obnoxious pop ups on your MacBook. It will trigger nag screens that try to brainwash you into thinking that your laptop is badly infected or has numerous performance issues. The goal of this tactic is to dupe you into buying the license and thereby take care of the alleged problems. To block these pop ups, you need to uninstall the impostor app using a specially crafted removal procedure.

Harmful code is heterogeneous by design and objectives, so there is no one-size-fits-all symptom that would apply to every malware predicament. However, a number of telltale signals are shared across a vast majority of mainstream Mac virus attacks:

  • Sluggish system performance
  • Browser redirects leading to unwanted web pages
  • Pop up ads and random in-text links on websites
  • Recurring pop up alerts and scan reports from an app you don’t remember installing
  • Unauthorized encryption of your personal data paired with a ransom demand

If you encounter any of the above quandaries, be sure to check your Mac for predatory programs and delete their file traces. Keep in mind that lingering with the fix may complicate the troubleshooting afterwards as the viruses may download extra pests behind your back.
