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.
| Name | 'WARNING! MAC OS Is Infected' virus |
| Threat Type | Mac malware, Mac virus |
| Symptoms | Your Mac became slower than normal, you see unwanted pop-up ads, you get redirected to shady websites. |
| Distribution methods | Deceptive pop-up ads, free software installers (bundling), fake flash player installers, torrent file downloads. |
| Damage | Internet browsing tracking (potential privacy issues), displaying of unwanted ads, redirects to shady websites, loss of private information. |
| Malware Removal (Mac) | To eliminate possible malware infections, scan your Mac with legitimate antivirus software. Our security researchers recommend using Combo Cleaner. |
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.
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.

How to remove 'Mac OS X is infected (4) by viruses' from Mac?
What is 'Mac OS X is infected (4) by viruses'?
'Mac OS X is infected (4) by viruses' is a typical virus alert. Pop-up windows of this type appear only on untrustworthy, deceptive websites. Typically, people visit these sites unintentionally - they are redirected by potentially unwanted applications (PUAs), which cause unwanted redirects, deliver advertisements, and collect browsing-related information.
The 'Mac OS X is infected (4) by viruses' pop-up window informs people that their Mac computers are infected and operating systems are damaged. It urges users to take immediate action and to scan the system for viruses. It also encourages them not to ignore this warning and gives just one option: to click the 'OK' button. When clicked, another pop-up window called 'Security Recommendation for Macs' opens and states that the system could be vulnerable and the user should consider scanning it for viruses. It goes on to state that scanning the operating system for viruses will ensure that information such as credit card/banking details, emails and account passwords, Facebook, Skype and other chat logs, photos, other data, and the webcam are safe and secure. This pop-up encourages users to download and install potentially unwanted apps such as MacKeeper for this purpose. If the 'Start Now' button is clicked, it starts the download/installation process of a PUA, which is supposedly anti-virus software or another such tool.
Installed PUAs usually cause redirects to deceptive websites, which are used to promote other unwanted, potentially malicious apps. These redirects to untrustworthy websites are not the only problem. Most PUAs gather information such as IP addresses, geo-locations, search queries, URLs of visited websites, and so on. In some cases, they target personal/private information. Developers share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue. The behaviour of PUAs and their developers can lead to problems relating to privacy, browsing safety, or even identity theft. Furthermore, many PUAs feed unsuspecting users with coupons, banners, surveys, pop-ups, and other intrusive ads. These are annoying and, if clicked, often open dubious websites or even run scripts that download/install other unwanted apps. If you believe an app of this type is installed, remove it immediately.

| Damage | Internet browsing tracking (potential privacy issues), displaying of unwanted ads, redirects to shady websites, loss of private information. |
| Malware Removal (Mac) | To eliminate possible malware infections, scan your Mac with legitimate antivirus software. Our security researchers recommend using Combo Cleaner. |
The number of deceptive websites designed to promote scams is countless, however, some examples include 'Apple.com-clean-os.live', 'APPLE.COM RECOMMENDS', and 'Your OSX 10.11 El Capitan Is Infected With 3 Viruses!'. Generally, these scams trick people into downloading and installing unwanted software. The software is usually presented as legitimate, however, none of these websites (or apps promoted through them) should be trusted.
How did potentially unwanted applications install on my computer?
Generally, unwanted apps are installed due to people clicking intrusive ads or installing/downloading software without paying attention to the details. Developers use the 'bundling' method, which allows them to trick people into downloading/installing unwanted apps together with regular software that they wish to download and install. They hide information about the bundling of unwanted apps in 'Custom', 'Advanced' and other similar parts of the software download or installation set-ups. Furthermore, many people install or download software in a hurry and leave available settings unchanged - this is how they cause unwanted installation/download of PUAs.
How to avoid installation of potentially unwanted applications?
You are advised to download all software using official and trustworthy sources (including direct links). Third party software downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, unofficial websites, and other similar sources should not be used. Additionally, check each available option (such as 'Custom', 'Advanced' and other similar sections) of any download/installation setup. Dismiss offers to download/install unwanted apps before finishing the download/installation process. Various intrusive ads should not be trusted, since they often redirect users to untrustworthy websites, such as pornography, gambling, adult dating, and other dubious websites. If you encounter unwanted redirects or intrusive ads, check for unwanted plug-ins, extensions, and add-ons installed on the browser, and programs on the computer/operating system. Remove all unwanted entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
