How to remove WARNING! MAC OS Is Infected from Mac?

What is WARNING! MAC OS Is Infected?

'WARNING! MAC OS Is Infected' is a fake error similar to Apple Security Alert, Apple Support Center - Attention!!, Apple Warning Alert, and many others. This error is displayed by a malicious website that users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs). These programs also deliver various 'malvertising' ads (pop-ups, banners, coupons, etc.), record information (mostly, about web browsing habits), and misuse system resources.

This error states that the system has been infected and that the malware must be removed and system repaired immediately. Users are advised that they must not hesitate to call Apple technical support via the telephone number ('1-844-658-5859') provided. Certified technicians then supposedly guide users through the malware removal process. Bear in mind, however, that 'WARNING! MAC OS Is Infected' is a scam. This error is fake and has nothing to do with Apple. In fact, cyber criminals claim to be certified technicians and attempt to monetize their services that are not needed. In addition, these people often trick users into granting remote access to their computers. Once connected, cyber criminals stealthily install malware and/or change system settings. Then they claim to detect additional errors and offer further help for an additional fee. Therefore, we strongly advise you to ignore 'WARNING! MAC OS Is Infected' and to never call the aforementioned telephone number. This error can be removed by closing the web browsing or rebooting the system. Be aware that some malicious websites and PUPs mine cryptocurrency or run other unwanted processes in the background. They misuse system resources without users' consent, thereby significantly diminishing overall computer performance. Potentially unwanted programs are also known to gather various information that might contain personal details. This data is sold to third parties. Furthermore, PUPs often deliver malicious ads using various tools that enable placement of third party graphical content on any site. Therefore, the ads usually conceal underlying content, thereby diminishing the browsing experience. Malicious ads may also lead to rogue websites and/or execute scripts that download and install malware. Therefore, even accidental clicks can result in high-risk computer infections. For these reasons, we advise you to uninstall all potentially unwanted programs immediately.

As mentioned above, 'WARNING! MAC OS Is Infected' shares many similarities with dozens of other fake errors. Each and each one claims that the system is damaged , however, these false claims are merely attempts to extort money from unsuspecting users. Potentially unwanted programs are also very similar. By offering various 'useful features', PUPs trick users into believing that these programs are legitimate and useful, however, that all potentially unwanted programs only generate revenue for the developers. Therefore, only very few give real value for regular users. Most merely promote rogue websites (unwanted redirects), deliver malicious ads, gather information, and misuse system resources. These programs pose a direct threat to your privacy and Internet browsing safety.

• Advanced Mac Cleaner is a bogus application, not a virus but not harmless too. This kind of application that you don’t need or which can’t do any good for Mac will only use extra space on your system and use your Mac resources which will cause slow system speed.

How did potentially unwanted programs install on my computer?

Research shows that some PUPs have official download websites, however, most are distributed using a deceptive marketing method called 'bundling', and via the aforementioned malicious ads. Therefore, users often install PUPs inadvertently or PUPs stealthily infiltrate their systems without permission. Bundling is stealth installation of third party software together with regular apps. Developers hide bundled programs within the 'Custom/Advanced' settings or other sections of the download/installation processes. Many users are careless during download and installation - they rush and skip steps. In addition, many users click various ads. This behavior often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Therefore, pay close attention when downloading/installing software and browsing the Internet in general. If possible, select the 'Custom/Advanced' settings, carefully analyze each window of the download/installation dialogues, and decline offers to download/install third party programs. Bear in mind that third party download/installation tools are monetized by promoting dubious programs (the 'bundling' method). Therefore, we recommend that you avoid using such tools - your software should be downloaded from official sources only, using a direct download link. Most malicious ads appear legitimate, as developers invest a great deal of time and money into their design, however, these ads are distinguishable for their redirects - most lead to survey, adult dating, pornography, and other similar sites. Therefore, if you encounter this type of ad or website, immediately remove all suspicious apps and browser plug-ins.

Learn why the Mac Cleanup Pro app is considered malicious, what it does to an infected Mac, and how to uninstall this pseudo system optimizer in a few steps.

Update: October, 2019

The nuts and bolts of hassle-free Mac usage involve periodic maintenance aimed at deleting software leftovers, Internet cache and other unneeded data the operating system and apps routinely generate. There are plenty of nifty tools out there that do the optimization trick. The utility called Mac Cleanup Pro, however, has nothing to do with junk removal done right. It deliberately reports low-severity or nonexistent macOS issues, flagging them critical and offering its paid performance enhancement service. No matter how well-tuned your system is and how scrupulously you’ve been keeping the hard disk space in optimal condition, this application will “detect” numerous issues regardless and emphasize the high improvement potential that can be allegedly squeezed out of the areas it purports to cover.

Speaking of the scan areas, the GUI of Mac Cleanup Pro lists the following: cache, logs, trash, extra languages, Internet history, login items, duplicates files, large files, and rogue apps. The latter, by the way, is really interesting because the program is outright scareware itself. Some insights into its genealogy reveal a direct relation to the most infamous family of bogus Mac optimizers as yet, which is also represented by such malicious heavyweights as Mac Auto Fixer, Advanced Mac Cleaner, Mac Tonic, and the recent one called Similar Photo Cleaner. Hailing from the same rogue cradle, Mac Cleanup Pro is backed by a sizeable distribution campaign that has allowed it to reach thousands of computers already and keep on spreading. Let’s look into one of these propagation tricks.

The unprincipled developers of the scareware in question are known to engage a framework of misleading web pages to push their digital culprit. One of these landing pages is parked at lp.superutils.co/adsph/2/ domain. The site includes a script that determines and displays the visitor’s country and IP address – this way, the users are more likely to fall for the deceptive tactic. A big giveaway, though, is that the “OS version” field says the victim uses OS Sierra, even if they visit the page from a Windows PC. Anyway, the site displays a warning that goes, “Your Mac Might Be Infected!” and provides some pseudo details, namely: “Your Mac might be infected by the latest viruses. If you do not remove them, they may damage your system files and slow down your Internet browsing speed.” (macOS Catalina 10.15 update: “helpermcp will damage your computer. You should move it to the Trash”). To get rid of the viruses (which aren’t there for real), the user is instructed to download and run Mac Cleanup Pro, which is dubbed “Mac Cleaner” on the phony page. Incidentally, another likely source of contamination is a site that renders a counterfeit alert saying “Your Mac is infected with 3 viruses”.

There are two possible ways that Mac users end up on lp.superutils.co/adsph/2/ domain. One is via redirect activity bolstered by a PUA (potentially unwanted application) that infects one’s web browser and forces hits to the misguiding site. In this case, the user needs to get rid of the troublemaking browser add-on or plugin, which may be a nontrivial objective due to obfuscation and persistence mechanisms of these pests. The other way is through hacked websites or online ads that lead to the scareware’s landing page.

Mac Cleanup Pro may re-infect your Mac multiple times unless you delete all of its fragments, including hidden ones. Therefore, it is recommended to download Freshmac and scan your system for these stubborn files. This way, you may reduce the cleanup time from hours to minutes. Download Now_{Learn how Freshmac works and get insights into its Terms of Use. If the utility spots malicious code, you will need to buy a license to get rid of it.}

Mac Cleanup Pro is often accompanied by extra threats that allow the attackers to add one more layer of monetization to their fraudulent activity, aside from the scare tactic alone. The infections that typically arrive in the same bundle include TechSignalSearch and TechNetSearch, the former being more common. In fact, both of them share identical characteristics and goals. The objective is to hijack Safari, or whichever browser is the victim’s default one, and redirect their web traffic to Yahoo or Bing via a series of disreputable ad networks. In some cases, the infected users keep visiting tech support scam sites that display fake alerts about Mac health and security problems that aren’t actually there. The shenanigans of TechSignalSearch virus may also result in Internet connectivity issues, where the wireless and LAN connection goes missing at certain intervals, usually every couple of minutes.

Obviously, this type of offending code is subject to immediate removal, but this turns out to be easier said than done. First of all, although the TechSignalSearch.app entry can be found in the infected Mac’s Applications folder, moving it to the Trash only yields a temporary effect and the pest will reappear shortly. Secondly, the rest of the files may be hidden in the LaunchAgents folder, which is a place not every Mac user knows how to access. With that said, a special security procedure is required to spot and completely delete all the elements of the follow-up nasties.

Whereas Mac Cleanup Pro can arrive by means of different techniques, it behaves in the exact same fashion when on board any Mac. It pops up out of the blue and triggers system scans that return really unsettling results over and over. The app thus attempts to persuade the victim that their machine has hundreds of performance issues, ranging from superfluous cache to unused languages that take up a great deal of disk space. It will also notify the user how much space can be recovered in just one click. Predictably, the cleaning feature can only be unlocked by activating the full version of the program, which is a matter of making a payment. This is precisely what the gist of the Mac Cleanup Pro virus is about. It frightens users into purchasing the full version. That’s a disgusting strategy, so there is, obviously, one reasonable way to treat the double-dealing program. Remove it now and mind what you download on untrustworthy websites further on.

FAQ

No, it’s not. Based on its unethical distribution practices and intrusive activity when on board a computer, Mac Cleanup Pro is flagged as a malicious application. Upon superficial inspection, it might seem that its makers are attempting to cash in on the growing demand for Mac optimization through third-party utilities. However, most users don’t even get a chance to familiarize themselves with its purported features prior to the installation, because the scareware infiltrates their systems in a stealthy way that has nothing to do with an informed decision. It mainly arrives as part of software bundles where the installation client’s default mode conceals the cross-promotion.

Aside from the surreptitious spreading, Mac Cleanup Pro deluges an infected Mac with pesky reports about performance issues that aren’t actually there. Fabricated scan results and follow-up alerts are the common symptoms of the attack.

Furthermore, the rogue optimizer additionally leaves a footprint in the victim’s web browser by redirecting the Internet traffic to fraudulent sites that say the Mac is infected and push a “cleaner” which is a virus in disguise. In summary, Mac Clean Up Pro is not legitimate. It is a fake system utility that does not belong inside your Mac.

Commonplace updates of the operating system and the installed software are actually accompanied by some degree of background maintenance. However, a more thoroughgoing cleanup would imply certain initiative on the user’s end. macOS Sierra and later versions go equipped with a feature called “Optimize Storage”. You can configure it to remove iTunes multimedia content you’ve already watched and handle email attachments in such a way that they won’t be automatically downloaded onto your hard disk. There is additionally an option to empty Trash automatically.

Create bootable dmg from windows. The system also allows you to empty caches and reduce clutter such as large files and the items you probably don’t need anymore. This type of optimization, though, relies on user involvement and cannot be scheduled or otherwise pre-assigned.

Mac Cleaner Spam Adds Safari

At the end of the day, Apple does perform some tidying as long as you configure your Mac appropriately, but a more tangible effect presupposes your action. One way or another, outsourcing this job to a program like Mac Cleanup Pro is a bad idea. You’re better off sorting through your junk files manually or downloading a trusted cleaner from the official store.

Mac Cleaner Scam Or Real

There is no on-demand virus scanner built into your Mac. Nevertheless, Apple delivers decent real-time protection against dubious apps you may want to install, plus its Gatekeeper module will generate an alert if a piece of third-party software has been covertly altered since it was last checked. Software updates also maintain an important layer of security through patches of the recently discovered vulnerabilities.

If you need to run a virus scan at will, though, this is doable with a specially crafted tool made by a reputable AV vendor. Be sure to download a security suite of choice from the official Mac App Store only, otherwise you may unknowingly expose your system to a rogue program like Mac Cleanup Pro.

Mac Cleanup Scam

Contrary to a common opinion, Macs aren’t flawless when it comes to self-optimization. You need to do quite a bit of the tedious cleaning work literally by hand to make sure the system runs smooth at all times. Therefore, a third-party app that automates the process of releasing disk space and boosting the Mac’s performance is more than welcome.

Thankfully, there are plenty of reliable Mac cleaners on the market. From where we stand, the apps called Combo Cleaner, Freshmac and MacBooster are among the top utilities in this niche. In addition to identifying and wiping memory hogs along with junk files you don’t need, these tools boast privacy and security essentials to keep your Mac experience both hassle-free and safe.
