Avoid the "Your Mac is infected with 5 viruses!" scam

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

This deceptive website is designed to promote another scam ("Norton subscription has expired today") and trick visitors into believing that their Mac computers are infected with viruses. It claims that, to remove the viruses, visitors must renew their antivirus software subscriptions.

In fact, this web page promotes a potentially unwanted application (PUA), which has nothing to do with Norton AntiVirus or any other legitimate antivirus software.

This web page suggests that the visitor's Mac is infected with five viruses and the antivirus software requires an update. To remove all 'detected viruses', the visitor is urged to update the installed antivirus software by clicking the "Proceed" button, and then download a program (a PUA) from the opened website.

In most cases, scam websites of this type are designed by scammers who attempt to trick visitors into installing browser hijackers, adware-type applications, or other PUAs. Note that no software should be downloaded from or through unofficial, dubious websites.

Typically, users do not open these websites intentionally - they are opened when people click deceptive advertisements, visit other dubious web pages, or have PUAs installed on their browsers and/or operating systems.

Note that PUAs can be designed to gather information relating to users' browsing habits such as IP addresses, geolocations, entered search queries, addresses of visited pages, etc. They might also collect personal (sensitive) data. The developers often sell the details to third parties (potentially, cyber criminals) or misuse it to generate revenue in other ways.

PUAs can also serve various advertisements. For example, pop-ups ads, coupons, banners, surveys. When clicked, these open untrusted, potentially malicious pages or even execute scripts designed to download and install unwanted applications.

Some more examples of scam websites designed to deceive visitors into installing PUAs 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 or used as a download source for files or applications.

If a browser opens a scam websites due to installed PUAs, remove the rogue apps immediately.

How did potentially unwanted applications install on my computer?

Generally, users download and install PUAs during the download/installation processes of other software. I.e., when the apps are included into the set-ups. In most cases, offers to download and/or install PUAs are mentioned in "Custom" and "Advanced" settings.

Many users fail to check and change these settings, thereby allowing PUAs to be downloaded and installed with other, regular software. This distribution method is known as "bundling". Additionally, unwanted downloads and installations can be caused by clicking deceptive advertisements that run certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to download files and software only from official websites and via direct download links.

Other tools and sources such as third party downloaders/installers, unofficial pages, Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used, as they can infiltrate unwanted software. Check "Custom", "Advanced" and other similar settings, and decline offers to download or install additionally-included unwanted apps.

Do not click ads that are displayed on dubious websites, since they can open other, potentially malicious websites or even cause unwanted downloads and installations by executing certain scripts. Remove any suspicious extensions, plug-ins and add-ons installed on the browser, and programs of this kind installed on the computer.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.
