E.tre456_worm_osx is a made-up name of a trojan virus used by scam alerts to scare and attack Mac users. This fake virus warning is displayed on websites with addresses like Apple.com-fixing.live, Apple.com-scan.live, and Apple.com-fast.live. Despite including the words “apple” and “mac”, these addresses belong to scammers.
E.tre456_worm_osx claims that it is related to the AppleCare Protection Plan, but in truth, it is operated by online criminals. Their goal is to force you to download and install a wide range of PUPs (potentially unwanted programs). For example, interacting with the alert may lead you to the installation of Mac Mechanic, Mac Cleanup Pro, CleanupMy-Mac, or other fake system optimization utilities.

What the E.tre456_worm_osx alert looks like
The E.tre456_worm_osx fake trojan virus attacks all Mac browsers, including Safari, Google Chrome, and Mozilla Firefox. As soon as the E.tre456_worm_osx fake alert appears, the browser gets hijacked and users are not able to close the window. This is the first message displayed by the alert:
Immediate action required

Clicking on the “OK” as instructed by the pop-up gives another message:

The E.tre456_worm_osx fake trojan virus alert displays your Mac version, the current date, and it may even show your IP to make itself look authoritative. And it shows a countdown to the supposed doom of your Mac. (In reality, nothing happens if you let the countdown run out.)
There is a very similar scam to E.tre456_worm_osx – E.tre456_worm_Windows. This one targets Windows users instead of macOS users. Overall, the two fake virus messages are very similar and they both seek the same thing: to get their victims to send their hard-earned money to scammers.
The goal of the fake trojan virus
E.tre456_worm_osx is meant to make you click on its “Scan Now” button. This leads to a fake scan of your Mac. Very quickly, the pseudo scan is completed and the alert shows many other threats that were supposedly found, such as Tapsnake, CronDNS, and Dubfishicv.
The E.tre456_worm_osx alert then instructs you to download some software that is going to fix the made-up Mac problems and remove the E.tre456_worm_osx trojan virus. It asks you to click on the final button, “Remove Viruses Now”. Doing that downloads and installs one of the PUPs mentioned in the very first paragraph of this article.
It is strongly advised that you do not download anything suggested by the E.tre456_worm_osx online scam. This will not fix your Mac, as it likely doesn’t need any fixing. Instead, it will make it even more burdened by useless utilities that slow down the system and flood you with even more fake virus alerts. Furthermore, the programs promoted by E.tre456_worm_osx are paid, meant to scam you out of your money.
How to remove E.tre456_worm_osx pop-ups

Even when you know that the E.tre456_worm_osx alert is a scam, it still makes you waste your time closing the pop-up window, which is disruptive and annoying.
