Avoid being scammed by websites claiming "(3) Viruses has been detected"
Written by Tomas Meskauskas on (updated)
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 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 typically 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" overview
Once a website running the "(3) Viruses has been detected" scam is accessed, it displays a pop-up stating that users have a notification concerning their iOS device. 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. Note that all the claims made by the "(3) Viruses has been detected" scam are false.
Software promoted by such schemes is usually nonoperational, untrustworthy, and it can even be malicious. These scams commonly endorse fake anti-viruses, adware, browser hijackers, and other PUAs. The presence of this software on devices can result in system infections, severe privacy issues, financial losses, and even identity theft.

Online scams in general
"Your Apple iPhone is severely damaged by 19 viruses!", "AdBlocker Update", "Your Apple iPhone is severely damaged by (6) viruses!" are some examples of 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, reveal personal information, call fake 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?
Deceptive/scam and other suspicious websites are often force-opened by installed PUAs. These apps are proliferated using social engineering and various questionable distribution methods.
Some PUAs have "official" download pages. These applications are also spread via download/installation set-ups of other products. "Bundling" is the term defining this marketing technique. Additionally, once clicked on, 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 available options, use the "Custom/Advanced" settings, and opt-out of all additions. 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 suspicious 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.
