What is "Your Mac is infected with 4 viruses"?

"Your Mac is infected with 4 viruses" is a fake virus alert that gets opened when a scam website is visited. Like most scams of this type it has one purpose, to trick people into downloading some application, in this case cleaning software for Mac computers. Typically, websites of this type are opened by potentially unwanted apps (PUAs) that people have installed on their browsers or computers. These apps often feed users with intrusive ads and gather various data too.

Your Mac is infected with 4 viruses scam

Once visited, this deceptive page displays a pop-up window that is presented as "Important alert". This website says that it detected four viruses and encourages its visitors to click "OK" to begin the repair process. It runs a fake virus scan that, once finished, it says that a computer is infected with a couple of Trojans, adware-type program and some other virus. Scan results are displayed in a window that is disguised as macOS Security Center which urges people to remove these viruses as soon as possible, or they might cause system damage, data loss and so on. Users are encouraged to download some newest cleaning software by clicking the "Download" button. Note that Apple company has nothing to do with software that is promoted through this scam or with the scam itself. It is not recommended to download any programs from websites of this type, if opened, they should be ignored/not be taken seriously.

As we mentioned in out introduction, most people end up visiting scam websites because they have some PUAs installed on their browsers (or computers). However, apps of this type often are designed to gather various data as well. Once installed, they start to gather various data such as IP addresses, URLs of visited websites, entered search queries, geolocations and other information of this kind. Some of them record personal details too. Their developers share all gathered data with other (third) parties who misuse it to generate revenue. Some of these parties might be cyber criminals. Another issue with having apps of this type installed is that they often display intrusive ads as well. Various coupons, banners, surveys, pop-up ads and so on. Usually they cover contents of visited websites and, if clicked, redirect people to untrustworthy websites or execute scripts designed to download and install other unwanted apps. These apps might lead to privacy, browsing safety issues, or even cause identity theft. We strongly recommend to remove apps of this type from browsers/computers immediately.

"Your Mac is infected with 4 viruses" is just one of the many scams that are created with a purpose to trick people into downloading various unwanted apps. Other examples are "Mac OS X Is Infected (4) By Viruses", "APPLE.COM RECOMMENDS" and "Your OSX 10.11 El Capitan Is Infected With 3 Viruses!". Apps promoted through such scams should not be trusted, downloaded or installed.

How did potentially unwanted applications install on my computer?

Typically, people install PUAs unintentionally. Inadvertent downloads and installations usually happen when users click on various intrusive ads or software developers use a deceptive marketing method "bundling". They use this method to trick people into downloading and installing unwanted apps together with other software. As a rule, they achieve it by hiding unwanted apps in "Custom", "Advanced" and other similar settings of software's download or/and installation setups. Information about PUAs being included in setups is not disclosed properly. People download and install these apps when they skip download or installation steps without checking any available settings.

How to avoid installation of potentially unwanted applications?

Always download software using legitimate, official and trustworthy sources. Avoid using third party software downloaders, Peer-to-Peer networks like torrents, eMule, unofficial sites and other similar sources for that. Install software with care, do not finish any installation without checking all the available "Custom", "Advanced" and other settings and dismissing offers to download/install unwanted apps first. Intrusive ads that are displayed on questionable pages often look legitimate, however, they cause unwanted redirects websites like gambling, pornography, adult dating and other similar websites. If these redirects and unwanted apps are a constant problem, check your web browser for any suspicious extensions, plug-ins or add-ons and remove all unwanted apps. Apply this to all unwanted programs installed on a computer as well. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
