How to remove “ZEUS Virus Detected” pop-up scam from Mac

What is “ZEUS Virus Detected” pop-up

ZEUS Virus Detected is a forged virus-alert message designed for Mac users that can appear in a browser as a result of suspicious redirects. Usually, these kinds of redirects are happening inadvertently when clicking on ads, however, sometimes they can be seen due to Potentially Unwanted Applications installed on your computer. The following message claims that your computer is infected with a malvertising piece that gathers your personal data like passwords, IP-addresses, geolocations and so on. Although, this is a type of scam that tricks users into calling the extortionists via the attached phone number to get paid instructions on how to get rid of the virus. More likely that frauds will offer to buy fake licensed software that will rectify the detected issues. Remember that this ostensibly official customer service is fake and has nothing to do with Apple meaning that the detected threat is fabricated and cannot be taken seriously. Moreover, your computer might be already virus-free and does not require any assistance. Of course, if you constantly see such messages when opening the browser, then this can be a result of PUAs sneaking on your computer and gathering the data to generate these kinds of redirects. We have prepared a full guide on how to remove the “ZEUS Virus Detected” pop-up from your computer.

How “ZEUS Virus Detected” pop-up infected your computer

As mentioned, these kinds of messages can be seen either due to inadvertent clicks on the web or some unwanted apps installed on your system. Potentially Unwanted Applications can be distributed via suspicious downloads, fake push-notification pop-ups and most importantly – bundling. Bundling means promoting additional software alongside different installation kits like repacks, for example. These offers are usually hidden in “Advanced” or “Custom” sections that are frequently overlooked. This means that people tend to skip unchecking the boxes for the appendant offers. This nonchalant behavior reflects in the installation of Unwanted Applications like adware without users’ consent. Subsequently, the adware will alter the browser settings for displaying various false messages like “ZEUS Virus Detected” pop-up. We strongly recommend removing this annoying pop-up from your computer by going through the instructions attached below.
