How to remove "Your system is seriously damaged, found (4) viruses!" from Mac?

What is "Your system is seriously damaged, found (4) viruses!"?

"Your system is seriously damaged, found (4) viruses!" is a scam created to promote/advertise a potentially unwanted application (PUA) called Cleanup My Mac. In fact, it might also be used to advertise other apps. These web pages are used to trick people into installing PUAs using deceptive methods. In any case, websites of this type and applications that are distributed through them cannot be trusted.

Your system is seriously damaged, found (4) viruses! scam

At first, this scam displays a pop-up window stating that the Mac OS X operating system is infected with four viruses and is damaged. Visitors are encouraged not to ignore this warning and to clean the system from these viruses immediately. Another pop-up states that detected viruses have already damaged 37.2% of the system, and unless they are removed immediately, they might damage system files, data, appendixes, and so on. Visitors are encouraged to click the "DOWNLOAD" button, which will then download the Cleanup My Mac program (the maccleaner.pkg file). According to this scam page, the button should lead to download of MacCleaner (another unwanted application). Note that "Your system is seriously damaged, found (4) viruses!" could be used to promote various applications at different times. In any case, none of the applications advertised on these sites can be trusted. Furthermore, all claims about 'detected viruses' are false. The best way to deal with these scam pages is to simply ignore and close them when they are opened.

In most cases, browsers open untrustworthy pages due to PUAs installed on the system, which force the websites to be opened. These apps can also display intrusive advertisements. For example, coupons, banners, surveys, pop-ups, and so on. When clicked, they open untrustworthy (possibly malicious websites) or run scripts that download/install other unwanted apps. Furthermore, apps of this type are often designed to gather information relating to users such as entered search queries, geolocations, IP addresses, URLs of visited websites, etc. In some cases, PUAs also record personal, sensitive details. Developers share the data with third parties who misuse it to generate revenue. These third parties might include cyber criminals.

There are many other scam pages on the Internet. Some examples are "Tiptoptrack", "You Have Been Redirected To Apple Support Page", and "Flash Player Might Be Out Of Date". No matter what their purpose, they can never be trusted. PUAs that open them are usually advertised as legitimate apps that supposed provide various features or useful tools. In fact, after installation, they deliver no real value. On the contrary, they simply help developers to generate revenue. This situation can lead to problems with privacy, browsing safety, and so on.

How did potentially unwanted applications install on my computer?

Typically, users do not download or install PUAs intentionally. This usually happens when they click dubious, deceptive ads or download and install various software. To trick people into unintentional downloads and installations, developers use a deceptive marketing method called "bundling". They add unwanted apps into the set-ups of other, usually free programs. Information about these additional downloads or installations can usually be found in "Custom", "Advanced", and other similar settings. Unfortunately, not all people check these setting and they fail to dismiss offers to download or install unwanted apps. Developers are aware of this and use it to their advantage.

How to avoid installation of potentially unwanted applications?

Do not download programs using untrustworthy sources such as third party downloaders, unofficial websites, Peer-to-Peer networks (torrent clients, eMule or other such tools), or other channels of this kind. Third party installers should not be used. The best way to download software is to use direct download links and official websites. Check "Custom", "Advanced", and other options/settings of any download or installation setup and dismiss offers to download/install extra software (unwanted applications). Intrusive advertisements, especially those displayed on rogue pages (relating to gambling, pornography, adult dating, etc.) should not be clicked. They can open potentially malicious websites or cause download/installation of unwanted apps. To stop the browser from displaying ads and/or opening dubious sites, remove suspicious, unknown or unwanted apps (extensions, add-ons, plug-ins) that are installed. If that does not solve the problem, it may be necessary to remove programs of this type that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
