How to remove apps downloaded via "Your Mac is infected with 5 viruses!" scam website from Mac?

What is "Your Mac is infected with 5 viruses!"?

This deceptive website is created with a purpose to promote another scam (named "Norton subscription has expired today") and to trick visitors into believing that Mac computer is infected with viruses. It claims that to remove those viruses visitors have to renew the antivirus software subscription, although, this page is designed to promote some potentially unwanted application (PUA) which has nothing to do neither with Norton AntiVirus or any other legitimate antivirus software.

Your Mac is infected with 5 viruses! scam

This page suggests that visitor's Mac is infected with 5 viruses and antivirus software requires an update. To remove all detected viruses a visitor is urged to update the installed antivirus software by clicking the "Proceed" button and then download some PUA from the opened website. In most cases scam websites of this type are designed by scammers who attempt to trick visitors into installing some browser hijacker, adware-type application, or other kind of PUA. In one way or another, no software should be downloaded from or through unofficial, shady websites. Typically, users do not open websites like this one intentionally, it is common that they get opened when users click some deceptive advertisements, visit other unreliable pages or have some PUA installed on a browser and/or operating system.

It is worthwhile to mention that PUAs can be designed to gather various information related to user's browsing habits like IP addresses, geolocations, entered search queries, addresses of visited pages, etc. Moreover, it is possible that a PUA could be designed to collect personal (sensitive) data as well. Another problem is that its developers may sell collected details to third parties (potentially cyber criminals) or misuse it to generate revenue in other ways. Another common issue with having such apps is that they are designed serve various advertisements. For example, pop-ups ads, coupons, banners, surveys. When clicked, they often open untrustworthy, potentially malicious pages or even execute scripts designed to download and/or install unwanted applications.

A couple more examples of scam websites designed to deceive their visitors into installing some PUA are "Warning: Your MacOS Has Expired", "ZEUS VIRUS DETECTED !!!" and "VPN Update". Whether a website of this kind is opened intentionally or not, it should never be trusted/used as a download source for any files or applications. If a browser opens a scam website because it has some PUA installed on it, then that app should be uninstalled right away.

How did potentially unwanted applications install on my computer?

More often than not users download and install PUAs during download and/or installation processes of other software. To be more precise, when apps of this type are included in various download, installation setups. In most cases offers to download and/or install PUAs are mentioned in settings of setups like "Custom", "Advanced" and so on. Unfortunately, quite often users do not check theose settings and by leaving them unchanged they allow for PUAs to be downloaded or installed together with some other, wanted software. This distribution method is known as "bundling". Additionally, unwanted downloads and/or installations can be caused by clicking deceptive advertisements: there are ads that cause it by running certain scripts.

How to avoid installation of potentially unwanted applications?

It is recommended to download files and software only from official websites and via direct download links. Other tools, sources like third party downloaders (or installers), unofficial pages, Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used - it is common that their users download and/or install unwanted software. Also, neither downloads or installations should not be finished without checking "Custom", "Advanced" and other similar settings and declining offers to download and/or install additionally included unwanted apps. Additionally, it is not safe to click ads that are displayed/appear on questionable websites. Very often they open other, potentially malicious websites or even cause unwanted downloads, installations by executing certain scripts. If there are any unwanted, suspicious extensions, plug-ins or add-ons installed on a browser and/or programs of this kind installed on a computer, then they should be removed (uninstalled) right away. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
