How to remove "(3) Viruses has been detected" from Mac computers

What is the "(3) Viruses has been detected" scam?

"(3) Viruses has been detected" is a scam run on various deceptive web pages. It claims that several threats have been detected on the device and recommends an untrusted piece of software to remove the fake viruses. This scheme targets iPhone users, however, it might also be accessed through other Apple devices. Scams of this kind are typically use to promote fake anti-viruses, adware, browser hijackers and other Potentially Unwanted Applications (PUAs). In some cases, these deceptive tactics are used to proliferate ransomware, Trojans and other malware. Few users access scam sites unintentionally - most are redirected to them by intrusive ads or PUAs.

(3) Viruses has been detected scam

Once a website running the "(3) Viruses has been detected" scam is accessed, it displays a pop-up stating that users have an important notification concerning their iOS device. After the pop-up is closed, the background page informs users that three viruses have been detected on their iPhones. These nonexistent threats have supposedly damaged the device's battery. To prevent further damage, the scheme instructs users to download/install a promoted application. The dubious virus protection tool will supposedly eliminate the fake malware and prevent further damage. Note that all claims made by the "(3) Viruses has been detected" scam are false. Furthermore, no website can detect threats/issues present on a device. Software promoted by such schemes is usually nonoperational, untrusted or even malicious.

Deceptive/scam websites are often force-opened by PUAs. These apps can cause redirects to other sites as well (such as sale-based, untrusted, rogue, compromised and malicious sites), however, these unwanted applications also have additional capabilities. They can enable the placement of various intrusive advertisements on any visited web page. When clicked, these ads redirect to likewise dangerous websites and can even execute scripts designed to stealthily download/install rogue software (e.g. PUAs). Other types of PUAs can hijack browsers - they modify browser settings and restrict/deny access to them to promote fake search engines. Most PUAs have data tracking capabilities. They can record browsing activity (browsing and search engine histories) and collect personal information (IP addresses, geolocations and other details). This vulnerable data is often shared with third parties (potentially, cyber criminals) intent on misusing it for profit. In summary, PUAs can cause system infiltration/infections, financial loss, serious privacy issues and even identity theft. To protect device and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

"Your Apple iPhone is severely damaged by 19 viruses!", "AdBlocker Update", "Your Apple iPhone is severely damaged by (6) viruses!" are some examples of other schemes targeting iPhone users. Online scams use social engineering and scare tactics to encourage people into performing specific actions. For example, to download/install and purchase dubious or malicious content, make monetary transactions (e.g. pay fake fees, bills, etc.), reveal personal information (e.g. names, addresses, telephone numbers, emails, banking account or credit card details. etc.), call fake and expensive service/support lines and so on. While such schemes make different claims and requests, the end-goal is identical: to generate revenue for the designers.

How did potentially unwanted applications install on my computer?

Some PUAs have "official" download pages, which are often promoted by deceptive/scam sites. These applications also proliferate via the download/installation set-ups of other products. "Bundling" is the term used to define this deceptive marketing technique of pre-packing regular software with unwanted or malicious additions. By rushing through download/installation processes (e.g. skipping steps, using pre-set options, etc.), many users risk inadvertent installation of bundled content. Once clicked, intrusive ads can execute scripts to download/install PUAs without users' permission.

How to avoid installation of potentially unwanted applications

You are advised to research all software prior to download/installation. Use only official and trustworthy download channels. Untrustworthy sources such as unofficial and free file-hosting (freeware) sites, Peer-to-Peer sharing networks and other third party downloaders should be avoided, as they can offer suspect content. When downloading/installing, it is important to read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, functions and so on. Intrusive ads may seem normal and harmless, however, they can redirect to dubious websites (e.g. gambling, pornography, adult-dating, etc.). If you experience these advertisements/redirects, inspect the system and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
