What is "e.tre456_worm_Windows"?

Virtually identical to "e.tre456_worm_osx Trojan", "e.tre456_worm_Windows" is the name of a fake trojan virus that is 'detected' by a deceptive website. Many scam websites are designed to trick visitors into believing that their computers are infected with viruses, malware, and so on. Typically, the main purpose of these pages is to advertise dubious software that supposedly removes the viruses. At the time of research, this particular site promoted MyCleanID. We advise against installing software that is downloaded from unofficial, deceptive pages. Note that people generally arrive at these pages due to potentially unwanted applications (PUAs) already installed on their browsers or operating systems.

e.tre456_worm_Windows pop-up scam

Visitors are encouraged to remove the aforementioned (e.tre456_worm_Windows) virus as soon as possible. The message in the pop-up, which is displayed after clicking "OK" in the first one, states that the Windows operating system is outdated and corrupted. To avoid loss of system files, visitors must supposedly follow the instructions provided. The background page states that the system is infected with three viruses: two classified as malware and one as phishing/spyware. It is mentioned that these viruses put visitors' banking and personal information at risk, and can cause loss of apps, photos, and other files. Visitors are encouraged to scan their systems by clicking the "Scan Now" button, which performs a fake system scan and leads to a download page of the aforementioned MyCleanID program. In fact, this scam page might also lead to download pages of other rogue software. In any case, no software that is promoted through deceptive, unofficial web pages should be trusted or downloaded/installed. Furthermore, this particular website is disguised as an official Microsoft site, however, Microsoft has nothing to do with this or any other scam websites. We recommend that you ignore the statements and close this website immediately. If it cannot be closed normally, end the browser process through Task Manager. Note that restoring the closed session will reopen this web page, so do not select this option.

As we mentioned, websites of this kind are often opened by PUAs, which are usually are designed to serve advertisements and gather data. They deliver intrusive ads such as pop-ups, coupons, banners, surveys, and so on. If clicked, these cause redirects to dubious pages or they execute scripts designed to download or install PUAs, or even malware. While installed, PUAs collect information such as IP addresses, search queries, URLs of visited websites, geolocations, and so on. Developers share the details with third parties (potentially, cyber criminals) who misuse them to generate revenue. The data might also contain personal, sensitive information. PUAs can thus lead to problems relating to browsing safety, privacy, and cause installation of malware or even identity theft.

Typically, scammers use these sites to trick people into downloading and installing rogue software. They display fake notifications about 'detected viruses' and encourage visitors to download programs that will supposedly remove them. Some examples of other scam pages are "VIRAL ALARM OF MICROSOFT", "Windows is not activated", and "This computer is blocked". PUAs responsible for redirects to these pages are generally very similar: they open untrustworthy pages, gather data, and feed users with unwanted ads. Typically, these apps are useless and designed only to generate revenue for the developers.

How did potentially unwanted applications install on my computer?

Frequently, people download and/or install PUAs inadvertently by clicking deceptive ads (that should not be trusted) or when software developers distribute unwanted software using the "bundling" method. This method is used to trick people into downloading and installing PUAs together with other, regular software. Developers include PUAs into the download or installation set-ups as additional offers, and place related information in "Custom" or "Advanced" settings. Many people download and install software without checking or changing these settings, thereby inadvertently allowing unwanted programs to be downloaded and/or installed by default.

How to avoid installation of potentially unwanted applications

Do not download or install software from untrustworthy websites, using third party software downloaders, installers, Peer-to-Peer networks such as torrent clients, eMule, etc. Use only official websites and direct download links. Opt-out of offers to download or install unwanted software before completing the download or installation procedure. Typically, these offers can be found in the aforementioned "Advanced, "Custom", and other similar settings. Avoid clicking intrusive ads, especially those on dubious web pages. These ads often redirect people to potentially malicious sites or cause download/installation of dubious software. Remove any unknown, unwanted extensions, add-ons, and plug-ins installed on the browser immediately. The same applies to software of this kind installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
