What is Your Mac Is Infected With 3 Viruses?

"Your Mac Is Infected With 3 Viruses" is a fake error message similar to Please Call Apple Support, Bankworm Virus, We Have Detected A Trojan Virus, and many others. It is displayed by malicious sites that users often visit inadvertently (they are redirected by potentially unwanted programs [PUPs] or intrusive advertisements delivered by other deceptive sites). Research shows that potentially unwanted programs typically infiltrate the system without permission and, as well as causing redirects, deliver intrusive advertisements and gather sensitive information.

Your Mac Is Infected With 3 Viruses scam

This error states that the computer is infected with a number of viruses and encourages users to immediately scan the system. Be aware, however, that this is a scam - "Your Mac Is Infected With 3 Viruses" error is fake. Cyber criminals employ this scam model to proliferate fake system optimization/anti-virus tools. Users are encouraged to download software that will 'remove' allegedly existing viruses, however, these applications are typically designed to display long lists of infections that do not exist. Furthermore, 'free versions' of these apps are supposedly incapable of removing the listed infections. Therefore, users are encouraged to purchase the 'full version'. This error is fake and you should never download any promoted software. If you have already done so, delete it immediately and certainly do not purchase any full version. The "Your Mac Is Infected With 3 Viruses" error can be removed simply by closing the web browser, however, some rogue sites employ scripts that prevent users from closing browsing tabs/windows. In these cases, terminate the browser using Task Manager or simply reboot the system. The next time the browser is opened, do not restore the previous session, otherwise you will end up reopening the malicious site/s.

Potentially unwanted programs deliver various intrusive advertisements, such as coupons, banners, pop-ups, and so on. These ads are delivered using tools that enable placement of third party graphical content on any visited website. Therefore, they often conceal underlying content, significantly diminishing the web browsing experience. Furthermore, intrusive ads can lead to malicious websites and even execute scripts that stealthily download and install malware/PUPs. Therefore, even a single click can result in high-risk computer infections. Another important issue is data tracking. Research shows that potentially unwanted programs gather information such as IP addresses, websites visited, pages viewed, search queries, keystrokes, and so on. The data often includes personal details that developers sell to third parties. These people (potentially, cyber criminals) misuse private information to generate revenue. Therefore, data tracking can lead to serious privacy issues or even identity theft. For these reasons, potentially unwanted programs must be uninstalled immediately.

As mentioned above, "Your Mac Is Infected With 3 Viruses" shares many similarities with dozens of other fake errors. All state that the system is damaged (e.g., infected, missing files, and so on), however, these claims are merely attempts to scare and trick users into calling fake 'tech support' (and pay for unnecessary services) or using deceptive applications. Potentially unwanted programs also share many similarities. By offering "useful features", PUPs attempt to give the impression of legitimacy, however, these applications are designed only to generate revenue for the developers. Rather than delivering any real value for regular users, PUPs cause unwanted redirects, gather sensitive data, and deliver intrusive advertisements, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Some PUPs have official download websites, however, in most cases these programs infiltrate systems without consent, since developers proliferate them using intrusive advertisements and the "bundling" method (stealth installation of third party applications together with regular software/apps). Developers do not disclose "bundled" PUP installations properly - they hide them within "Custom/Advanced" settings (or other sections) of the download/installation processes. In addition, many users rush these procedures, skip steps, and click advertisements without understanding the possible consequences. In doing so, they expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Be aware that intrusive advertisements may seem legitimate and useful, but once clicked, redirect to gambling, adult dating, pornography, and other similar dubious websites. If you encounter such ads, immediately eliminate all suspicious applications and browser plug-ins. Furthermore, select "Custom/Advanced" settings and closely analyze each window of the download/installation dialogs. Opt-out of all additionally-included programs and decline offers to download/install them. Software should be downloaded from official sources only, using direct download links. Third party download/installation tools often include rogue applications, and thus should never be used.
