removal by Gabriel E. Hall - - | Type: Adware is a fraudulent website that claims Mac computer compromise by e.tre456_worm_osx or another virus is a scam that was compiled by threat actors. It usually begins with adware infection – ad-supported software gets into machines with the help of software bundling or is installed intentionally when users do not spot the deception. Soon after the infiltration, the potentially unwanted program displays a significant amount of pop-ups, banners, deals, offers, in-text links, and other forms of ads.

The infected Google Chrome, Safari, Mozilla Firefox, or another browser starts linking users to insecure domains, and is one of those. As soon as the visitor enters the site, a pop-up shows up which suggests that Mac is infected with the e.tre456_worm_osx trojan and that immediate action is required to fix the issue.

Allegedly, the only way to address the problem is by performing a fake scan within the browser, which later asks users to download bogus software, such as Cleanup My Mac, Advanced Mac Cleaner, or similar scareware.[1] As evident, these tools are useless, and the claims are fake – no trojan is affecting the device.

Nevertheless, to remove redirects from the web browsers, adware must be terminated either with the help of security software or our manual removal guide below.

Adware, such as the one that redirects to, is by far not the most devastating computer infection, although security experts already warned about its dangers, and some even suggest called it malware due to its deceptive techniques that are used by the latter.[2]

In the recent years, many scandals emerged, such as Lenovo Superfish adware campaign,[3] suggesting that adware can be just as dangerous as malware, compromising users' online safety by exposing them to potential cyber attacks. Regardless of the controversy, adware is here to stay (at least for now), and users should take care of their computers if they value their online security and computer safety, avoiding such scams as

Those who get redirected to site would see a pop-up which claims:


We have detected a trojan virus (e.tre456_worm_osx) on your Mac.

Press OK to begin the repair process

This is a very common scare tactic that is used to frighten inexperienced users by claiming virus infections. However, more computer-savvy individuals would know straight away that browser-based scanners cannot determine whether or not your system is infected. Therefore, it becomes apparent that virus is fake, and there is no need to proceed with fake scans.

Nevertheless, those who get tricked will be prompted to download and install fake system optimization tools that work similarly to tech support scams, claiming multiple computer threats. Later, users are asked to pay for the full license of the application, resulting in money loss, as there is no proof that the app was installed on the system with the help of phishing.

Therefore, if you see persistent ads and redirects to scam sites, you need to proceed with removal, which would involve terminating adware from macOS. You can employ security software that specializes in PUPs or terminate the infection by following our guide below.

Do not trust software bundles – expand the installation list of optional components by opting for Advanced settings 

While there is a chance that you installed adware intentionally (and do not know about it yet), the vast majority of PUP infections from software bundles. If the former is the case, it might sometimes be difficult to determine which application is ad-supported, especially if you use many of them.

In most cases, users rush the installation process, and do not pay close attention to instructions, skipping vital steps. And that is precisely what freeware and PUP developers are looking for, as they can hide optional components within the installers in a way most rushing users would never notice. For example, they use a misleading placement of buttons, grayed out options, pre-ticked boxes, and other tricks. 

To avoid the deception, never rush the installation process and always read through the instructions. Make sure you select Advanced/Custom mode and terminate all the optional installs before proceeding. Additionally, check if vital documents like Privacy Policy and Terms of Service are provided, lack of which might indicate that you are installing an unsafe program.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
