How to remove "Your Mac/iOS may be infected with 5 viruses!" from Mac computers

What is "Your Mac/iOS may be infected with 5 viruses!"?

"Your Mac/iOS may be infected with 5 viruses!" is a pop-up window displayed by deceptive/scam websites. It employs scare tactics to encourage visitors into taking certain actions, which result in them being redirected to various untrustworthy and malicious sites. The pop-up alerts users of viruses it has supposedly detected on their devices and offers to update their antivirus software. No web page can find threats/issues on systems, and any that make these claims cannot be trusted. Rogue websites are usually accessed inadvertently via redirects caused by intrusive advertisements or Potentially Unwanted Applications (PUAs) installed on the browser/system.

Your Mac_iOS may be infected with 5 viruses! scam

Once the deceptive site is entered, it displays a pop-up which claims to perform a system scan. The results inform visitors that their Mac/iOS might be infected with five viruses. The pop-up window states that immediate removal is required, as users risk permanent data loss and further system damage (implying that it has already suffered some). Additionally, visitors are warned that their personal and banking information is endangered. To further give the impression of legitimacy, it lists the virus names, types, threat levels, and infected files. To eliminate these alleged threats, the device's antivirus software apparently needs an update. Users are urged to click the "Proceed..." button to be redirected to the update download page. From here, they are to download the latest antivirus version. After the button is clicked, however, the scam site redirects users to random, potentially malicious web pages (where they are redirected depends on their geolocations). As mentioned, no website can find threats/issues present on visitors' devices. Often, sites that display alerts such as "Your Mac/iOS may be infected with 5 viruses!" endorse bogus, nonoperational software. These advertised products typically require activation to be perform their functions (i.e., require purchase in order to work). Despite being activated (purchased), they usually remain nonfunctional. Note that MacCleansePro, K9-MacOptimizer, and Qbit Mac Optimizer are just some examples of these fake applications. Note that "Your Mac/iOS may be infected with 5 viruses!" promotes Intego, which is legitimate software, and yet endorsed by rogue ad networks.

As well as generating redirects to dubious and malicious web pages, PUAs have other dangerous capabilities. They can run intrusive advertisement campaigns. By employing various tools, they enable third party graphical content to be displayed on any site, thereby delivering ads (pop-ups, banners, coupons, surveys, etc.) that significantly diminish the browsing experience (by limiting browsing speed and web page content visibility). Furthermore, due to the harmful sites to which they redirect and for their ability to stealthily download/install PUAs, intrusive ads are a safety threat. Other unwanted apps can make unauthorized changes to browsers by hijacking them and promoting fake search engines. Many PUAs also have data tracking capabilities. They record users' browsing activity (URLs visited, search queries, etc.) and gather personal information (IP addresses, geolocations and other details). This sensitive data can then be shared with third parties (potentially, cyber criminals) seeking to misuse it for financial gain. To summarize, PUAs can cause browser/system infiltration and infections, and lead to financial loss, serious privacy issues and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately upon detection.

There are thousands of scams similar to "Your Mac/iOS may be infected with 5 viruses!" including, for example, "This Update Requires An Action", "Your Mac OS Might Be Infected", Your-mac-security-analysis.net, and many others. Commonly, these deceptions involve the using scare tactics. For example, some rogue websites alert users of false threats/issues found of their systems and attempt to trick them into downloading/installing or purchasing dubious software. These sites are rarely accessed intentionally, since most visitors are redirected by intrusive ads or PUAs.

How did potentially unwanted applications install on my computer?

Some PUAs have "official" download sites, on which they are frequently promoted as "free" and "useful", however, these applications can also be downloaded/installed together with other products. This deceptive marketing method of pre-packing regular software with unwanted or malicious content is called "bundling". Rushing download/installation processes (e.g. ignoring terms, using pre-set options, skipping steps and sections, etc.) increases the risk of allowing bundled apps onto systems. Once clicked, intrusive ads can execute scripts designed to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

Research content to verify its authenticity, before downloading/installing. Use only official and verified download sources. Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting websites, third party downloaders and similar channels are classed as untrustworthy and should be avoided. Approach download and installation processes with caution. Read the terms, study all available options, use the "Custom/Advanced" settings, and decline offers to download/install supplementary apps, tools, features, etc. Intrusive advertisements usually seem normal and harmless, however, they often redirect to dubious sites (e.g. gambling, pornography, adult-dating and others). If you encounter ads/redirect of this kind, check the device and remove all suspect applications and/or browser extensions/plug-ins without delay. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
