Remove MacKeeper popup from Mac (Safari, Chrome, Firefox)

Read this entry to stay on top of the MacKeeper popup issue, learn the mechanics of this hoax, and apply an effective and relevant virus removal technique.

There are various reasons why people prefer Macs over machines made by other manufacturers. One of them is the exceptional quality of the hardware and customer experience overall. Many users try to stay in vogue that way. A lot of Apple fans choose these products because of the outstanding security of the operating system. Unfortunately, the latter perspective is being undermined by a growing number of potentially unwanted applications (PUAs) that have heavily inundated the macOS ecosystem.

This holds true for the app called MacKeeper, which is a scareware sample disruptive and prolific enough to turn a part of the above mindset into an empty concept. This strain has got a notorious background that started up from a promising combo of performance booster and AV tool, with the reputation taking a nosedive after highly aggressive intimidation techniques took effect. This negative evolution, or rather degradation, has been accompanied by MacKeeper popups all the way.

Fake MacKeeper pop-up reporting junk files

Let’s look into this social engineering element of the sketchy program’s modus operandi. The popup activity by MacKeeper can be system-wide. No matter what app is currently opened, and even if it’s just the desktop that the user is on, the culprit might display an alert saying, “Clean up your Mac after visiting risky sites”. To make the whole deceit a bit more persuasive, the fake warning also shows the victim’s version of OS X or macOS, plus the country they are in. It goes on to say that a slew of junk files are hogging on the machine, and these items should be removed immediately otherwise they will slow down the system and take up a great deal of disk space.

A follow-up dialog will also appear, reading, “Please consider cleaning your Mac from junk”. There is a download button at the bottom that leads to MacKeeper. If the user falls for this trick, the rogue application will take a firmer grip on the system and generate fake scans one after another.

Another variant of the MacKeeper pop-up

As opposed to the above scenario, MacKeeper popups can be isolated to a web browser. While some people would think that’s the lesser of two evils, this is probably a misconception. Owning a computer doesn’t make much sense without web surfing, so this type of ads is an equally bad nuisance. One of the common forms of these alerts raises a pseudo red flag on viruses called Tapsnake, CronDNS, and Dubfishicv, which have been allegedly detected on the Mac. The pop up puts some extra pressure on the user by saying, “Your Mac is heavily damaged!” and emphasizes that the risk stemming from these threats is extremely high. Of course, this guile is complemented by a persistent recommendation to download and install MacKeeper and thereby allegedly get the issue fixed.

‘Your system is infected with 3 viruses’ alert pushing MacKeeper scareware

One more type of browser-borne phony warnings promoting the unwelcome software revolves around a spoof notification that goes, “Your Mac is infected with 3 viruses!” This campaign is so prevalent that the wording of the alert proper has become a buzz phrase. Unlike the Tapsnake scheme, though, no specific names of infections are indicated there. The offending artifice boils down to a statement that traces of 2 malware and 1 phishing/spyware items have been spotted on the computer. To instill trust, the pop up pretends to be from AppleCare Products or AppleCare Protection Plan. To top it off, a script runs on the page and reflects the amount of time left “before the damage is permanent”. Again, the victim is lured into clicking the Scan Now button, which points to MacKeeper or similar scareware from the same lineage. It’s also worth mentioning that this fake warning can be used in tandem with the Tapsnake fraud. In this case, it serves as the primary alert, and if the victim clicks “Scan Now” they are forwarded to the “Download required!” landing page listing the 3 imaginary threats.

It’s important to understand that the very fact of these pop-ups invading a Mac is a signal of malware presence on the computer. It could be a browser hijacker or adware that’s part of the ramified MacKeeper promotion wave. If the bogus warnings appear beyond the browser, the issue might be more serious and denote that the scareware is already on board and is now attempting to brainwash the victim into paying for its license. Either way, the problem won’t vanish on its own unless a fix is applied. Speaking of which, the sections below will guide you through.
