How to remove 'Your MacOS 10.14 Mojave Is Infected With 3 Viruses!' from Mac?
How To Run A Virus Scan On Macbook Pro Max
What is 'Your MacOS 10.14 Mojave Is Infected With 3 Viruses!'?
'Your MacOS 10.14 Mojave Is Infected With 3 Viruses!' is a fake virus alert message that is displayed for MacOS users who visit untrustworthy and deceptive websites. In most cases, users do not visit these websites intentionally - potentially unwanted applications (PUAs) cause these redirects. PUAs are installed without direct permission, cause unwanted redirects, deliver intrusive ads, and record browsing-related and other data.
The message in the 'Your MacOS 10.14 Mojave Is Infected With 3 Viruses!' pop-up window states that the Mac operating system is infected with a trojan virus (e.tre456_worm_osx) and immediate action is required. According to the claims, the system is infected with three viruses: two malware and one spyware infection. It goes on to state that if no action is taken, data such as apps, photos, and other files might be in danger and could be lost. The scammers behind this fake virus alert use it to promote software that, according to the message, will remove the viruses that were detected. At time of research, scammers promoted the Mac Cleanup Pro software. This is typical behaviour of scammers who use various fake messages. Generally, they claim to be 'technicians' (in this case, representatives of Apple) and either offer purchase of a product that will fix the problem (in this case, the virus infection) or attempt to trick people into paying for technical guidance or other services. Note that Apple has nothing to do with the 'Your MacOS 10.14 Mojave Is Infected With 3 Viruses!' virus alert. Do not download the software offered, and certainly do not pay for it. Ignore these fake alerts. Simply close the deceptive website and avoid returning to it in future. If it cannot be closed normally, use Activity Monitor and 'force quit' the entire browser. Do not restore the previous session.
PUAs mentioned in our introduction also deliver coupons, banners, and other similar intrusive ads. These are usually displayed via tools that enable placement of third party graphical content on any site. When displayed, they conceal underlying content of visited websites. If clicked, they might redirect to untrustworthy websites or even execute scripts designed to download/install other unwanted apps. Another downside of PUAs is that they gather browsing-related and other data. Typically, these unwanted apps record IP addresses, keystrokes, search engines, URLs of visited websites and other similar data. They also collect personal or sensitive data that PUA developers share with third parties (potentially, cyber criminals) who misuse it to generate revenue. Thus, PUAs can cause various problems relating to browsing safety, privacy, or even identity theft.

There are many fake virus, error, and other similar alert messages online, including Your OS High Sierra Is Infected With (3) Viruses!, Your Computer Was Locked, Mac OS Support Alert, and so on. Generally, scammers use these alerts to trick people into paying for services or products that will supposedly solve the 'problem'. PUAs are promoted as 'useful tools', however, these are only attempts to trick people into downloading and installing rogue software. These apps provide none of the functionality promised and are designed only to generate revenue for their developers.
How did potentially unwanted applications install on my computer?
Some potentially unwanted applications can be found on their official websites and downloaded from there, however, in most cases PUAs are installed through intrusive ads, third party software downloaders/installers, or when software developers use a deceptive marketing method called 'bundling'. Bundling is stealth installation of third party apps with regular (usually, free) software. Developers do not properly disclose information about the presence of bundled apps in installation set-ups - they hide them in 'Custom', 'Advanced' and other similar settings (options) of the download/installation processes. Developers are aware that many users skip installation steps without checking these settings, and they use this behaviour to their advantage.
How to avoid installation of potentially unwanted applications?
Do not use software downloaders, torrents or untrustworthy websites to download software. Use official websites or other sources, and direct links only. When installing, check all available 'Advanced', 'Custom' and other sections. Deselect unwanted offers (such as potentially unwanted programs) and only then finish the installation process. Be cautious when browsing the web and avoid clicking on intrusive ads. Most malicious advertisements seem legitimate, since developers invest time and money into their design, however, if clicked, they often redirect to untrustworthy websites (gambling, pornography, adult dating, and other similar sites). If you encounter these ads, or redirects caused by them, check for unwanted extensions, plug-ins, and add-ons installed on your browser, or unwanted programs installed on your computer. Remove any unwanted entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
