Update October 2019. A similar scam which is currently circling the web is called A website you visited today has infected your Mac with a virus. Note that this type of messages are displayed by bogus websites. Your browser can be redirected to such a website after a visit to another rogue site. On the other hand, it may be a potentially unwanted program that is running on your Mac that is causing the appearance of fake virus alerts. The texts of fake virus alerts may differ from scam to scam but the approach is always the same, and so are the scammers behind them.

Your Mac is Infected. Virus Found! Scam – Spread

In order to be introduced to the computers of victims, the Your Mac is Infected. Virus Found! scamming page has to be displayed with the help of a script or a program. If by script, this redirect may be caused as a result of you having to visit an unwanted website that should not be trusted. The most likely method via which such redirects appear however is if you have a potentially unwanted program also known as PUP that may be installed on your computer. These programs often find their way into your computer via the installers of other free apps you may have added to it. Such installers often aim to get users to add third-party apps as a form of a third-party promotion, whose primary goal is to advertise the unwanted app “as a free extra to the current installation”.

The bad news here is that these apps can easily be missed since they are often concealed well within the the installation steps, usually in the “Advanced” or “Custom” installation modes.

Text from image:

Notice: Your Mac is Infected. Virus Found!

Your Mac device has been infected by the latest unpatched malware. This virus is highly dangerous and can cause severe damage to your machine.


The message is extremely approximate to another scam which was also displayed for Mac OS systems and stated “Your system is heavily damaged by (4) virus!”. After thorough research of these types of scams, we have established that they can be seen on variety of devices, including iPhones and Android devices:

These scams often advertise the two same programs for Windows and MacOS:

  • PC Smart Cleanup (Windows).
  • MacKeeper (MacOS).

Once installed on your Mac machine, MacKeeper may start to conduct automatic scans of it in order to demonstrate that it has detected what appears to be fake detections. The scary part however comes when the user is fooled to trust this software and choose to remove the threats. MacKeeper then displays what appears to be a purchase form where the user is asked to enter his or her personal and financial information in order to pay a lot of money to purchased the licensed version of MacKeeper. Be advised that it is not advisable to do so, since the malware may not even exist on your Mac machine and the end goal of this is to scam you into paying the scammers.
But money is not the only thing you should be worried about in case you paid the scammers, because seeing the web page and installing MacKeeper can result in the scammers to employ various types of scamming technologies, like:

  • Pixels.
