How to remove 'Your Mac is infected with 4 viruses' from Mac?
MacOS has many features that help protect your Mac and your personal information from malicious software, or malware. One common way malware is distributed is by embedding it in a harmless. Stopping a virus altogether involves searching your Mac pretty thoroughly to ensure all traces of the virus are gone. You should use malware-scanning software to help identify and eliminate viruses.
What is 'Your Mac is infected with 4 viruses'?
'Your Mac is infected with 4 viruses' is a fake virus alert that appears when opening a scam website. Like most scams of this type, it attempts to trick people into downloading a dubious application - in this case, cleaning software for Mac computers. Typically, these websites are opened by potentially unwanted apps (PUAs) that people have installed on their browsers or computers. PUAs feed users with intrusive ads and gather data.
This deceptive page displays a pop-up window presented as an 'Important alert'. The pop-up states that the site has detected four viruses and encourages visitors to click 'OK' to begin the 'repair process'. It then runs a fake virus scan that, once finished, states that the computer is infected with a number of Trojans, adware-type programs, and other viruses. The scan results are displayed in a window disguised as macOS Security Center, which urges people to remove the viruses immediately, otherwise they might cause system damage, data loss, and so on. Users are encouraged to download the latest cleaning software by clicking the 'Download' button. Note that Apple has nothing to do with software promoted through this scam or with the scam itself. Do not download programs from these websites - ignore them and do not trust the statements.
As mentioned, most people end up visiting scam websites due to PUAs installed on their browsers (or computers). Note that PUAs also gather data. Once installed, they record IP addresses, URLs of visited websites, entered search queries, geolocations, and other information. Some PUAs also record personal details. Developers share the data with other third parties who misuse it to generate revenue. Some of these third parties might be cyber criminals. Note that PUAs often display intrusive ads such as coupons, banners, surveys, pop-up ads, and so on. These conceal underlying content of visited websites and, if clicked, redirect people to untrustworthy websites or execute scripts designed to download and install other unwanted apps. PUAs can thus lead to privacy/browsing safety issues or even cause identity theft. We strongly recommend that you remove all PUAs from your browsers/computers immediately.

'Your Mac is infected with 4 viruses' is just one of many scams designed to trick people into downloading 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 these 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 intrusive ads, or software developers use a deceptive marketing method called 'bundling'. They use this method to trick people into downloading and installing unwanted apps with other software by hiding unwanted apps in 'Custom', 'Advanced', and other similar settings of software download/installation set-ups. Information regarding the inclusion of PUAs in set-ups is not properly disclosed. Furthermore, many people download and install these apps inadvertently when they skip download/installation steps without checking the available settings.
How to avoid installation of potentially unwanted applications?
Download software using legitimate, official, and trustworthy sources. Avoid using third party software downloaders, Peer-to-Peer networks such as torrents, eMule, unofficial sites and other similar sources. Install software with care, do not finish any installation without first checking all available 'Custom', 'Advanced' and other settings, and dismissing offers to download/install unwanted apps. Intrusive ads displayed on dubious pages often seem legitimate, however, they cause unwanted redirects to websites such as gambling, pornography, adult dating, etc. If you experience these redirects and ads, check your browser for any suspicious extensions, plug-ins, or add-ons, and remove all unwanted entries. Also apply this to unwanted programs installed on your computer. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
