E.tre456_worm_osx virus Removal Guide

Description of E.tre456_worm_osx scam

E.tre456_worm_osx is a fake alert with tries to trick users into installing useless software

E.tre456_worm_osx virus

E.tre456_worm_osx is a bogus pop-up message which tries to scare Mac OS users and make them believe that multiple malware infections are threatening computer safety and personal data. There are two different reasons why users might be shown this fake message – they either get redirected from a malicious website or have an adware program installed on their machines.

Alternatively, victims might be exposed to a website without a pop-up where users can click on ‘Scan Now’ button. On a pop-up, the only option available is ‘OK’. Regardless, both of these will lead users to the installation of rogue security software on their machines. This program is entirely fake and does nothing to help your computer. Instead, you should remove E.tre456_worm_osx phony alert if you continuously get redirected to it.

The note displayed can vary, but, typically, users are shown this bogus message:

www.apple.com-macbook-secure.systems says:
We have detected a trojan virus (e.tre456_worm_osx) on your Mac.
Press OK to begin the repair process.

As evident, the alleged trojan infection is not real and your PC is not infected with any dangerous viruses (apart, possibly, by adware). If you see this fake alert, quickly close down your browser and then proceed with E.tre456_worm_osx removal.

The e.tre456_worm_osx scam can target any browser, including Google Chrome, Mozilla Firefox, Safari, Internet Explorer, and others. The developers did not think through the operation of the virus properly though, solely because the message displayed is directed to Mac users. However, a targeted computer might not even be a Mac. Hence, this is a first sign of the scam.

Nevertheless, individuals who do use Mac might be tricked into proceeding with the fake scan, especially if they never encountered any virtual scams before. Be aware that E.tre456_worm_osx virus developers put a lot of effort to make the message believable (there is a date, Apple logo and the whole design of the message is imitating Apple messages).

The bogus software installed can be in the form of adware, various browser extensions, fake optimization tools or other PUPs. Using these applications might harm user’s computer as these programs are known to eventually lead victims to phishing, scam or malicious websites where dangerous malware can be obtained.

Personal information can also be at risk. Cybercriminals might use social engineering skills to trick users into disclosing personal data (like home address, email, social media account passwords, social security number, credit card details, etc.) which can be used for illegal purposes. Thus, do not risk your safety and get rid of E.tre456_worm_osx as soon as you can. You can rely on reputable security software, like FortectIntego or eliminate the threat manually.

Distribution methods of suspicious programs

As we mentioned above, if you only got redirected to the malicious fake message/domain once, all you have to do is close down your browser. However, if you notice these redirects continuously, adware is is causing them.

Adware is an ad-supported software which displays various intrusive ads, deals, pop-ups, offers or even fake updates and messages, like E.tre456_worm_osx one. Unwanted applications typically are included in software bundles as additional components. Many users are still unaware of bundling tactics used by free software developers on a regular basis.

Thus, it is critical to be attentive while installing freeware obtained online. Before installing unknown programs, make sure you read up on them, as reviews online might disclose a lot of information. After you are confident that you want the program, make sure you read through Privacy Policy and EULA.

When you are prompted with a pop-up, asking you whether you want to pick Default or Advanced installation modes, you should always proceed with the latter. This way, you can decline any additional components which might be offered with the desired application.

How to prevent from getting adware

Prevent the government from spying on you

As there is a growing debate in government about collecting users' data and spying on citizens, you should take a closer look at this issue and find out what shady ways of gathering information can be used to collect information about you. You need to browse anonymously if you want to avoid any government-initiated spying and tracking of information. 

You can enjoy secure internet browsing and minimize the risk of intrusion into your system if you use Private Internet Access VPN program. This VPN application creates a virtual private network and provides access to the required data without any content restrictions.

Control government and other third party access to your data and ensure safe web browsing. Even if you do not engage in illegal activities and trust your ISP, we recommend being careful about your security. You should take extra precautions and start using a VPN program.

Recover files damaged by a dangerous malware attack

Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.

Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.

The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
