How to remove redirects to maztek[.]xyz from Mac computers

What is maztek[.]xyz?

maztek[.]xyz is a scam site, which claims that the visitor's device has been infected. Note that no web page can detect threats/issues present in systems. Typically, scams of this type promote untrustworthy and/or malicious content. At the time of research, maztek[.]xyz redirected users to a broken website. Most visits to this site occur via redirects caused by intrusive ads or Potentially Unwanted Applications (PUAs) already infiltrated into the device.

maztek[.]xyz scam

There are several variants of the scam run by maztek[.]xyz. One version displays a pop-up window stating that the visitor's iPhone has been compromised and immediate action is required. Closing this window displays another page. It clarifies that the device has supposedly been infected with nine viruses. Therefore, the browser has suffered significant damage from the viruses, which are identified as browser trojans. These fake viruses have apparently originated from visits to recently corrupted websites. Additionally, the trojans can proliferate and infect data such as Facebook accounts, Whatsapp messages, photos and other private apps. Therefore, users are provided with instructions about how to eliminate the threats. Firstly, they are urged to press the "REMOVE VIRUS" button and download/install a VPN from the App Store. They must then open the application and install the latest updates, thereby removing older, infected versions of it. Another variant of this scam also presents visitors with a pop-up, which is a bogus system notification. It notifies users that malware has been detected on their device and they must tap "OK" to initiate the repair process. Doing so, closes the window and the background page details that three viruses have been found on the user's iPhone. Allegedly, the device's battery has already been damaged by this malware. As per the previously described version, this one also urges users to immediately remove the viruses to prevent further damage. The step-by-step removal instructions instruct users to click "Download and Install", thereby installing the recommended free VPN and anti-virus tool from the App Store. They must then run this app and follow the instructions provided to remove the malicious software from their devices. Note that maztek[.]xyz and other sites making similar claims are all scams. Trusting them will not remove any threats, since all of the detected issues are fake and nonexistent. Following the above steps will simply allow PUAs or even malware onto devices. Never download/install or purchase products promoted via these dubious methods.

As well as force-opening deceptive web pages, PUAs can redirect to sale-oriented, rogue, compromised and malicious websites. In fact, unwanted applications have varying capabilities. They can deploy intrusive ad campaigns - resulting in ads that diminish the browsing experience (by causing redirects to likewise harmful pages and stealthily downloading/installing unwanted content). Other apps of this type modify browsers and limit or deny access to settings. Fake system cleaning/optimization software also falls within the PUA classification. These applications must be purchased to work (i.e., they require activation to perform the functions promised). Following payment, however, they remain nonoperational. PUAs commonly track data, with information of interest including (but not limited to) IP addresses, browsing and search engine histories, geolocations and other personal details. The only purpose of this software is to generate revenue for the developers at users' expense. PUAs can cause browser/system infiltration and infections, lead to financial loss, serious privacy issues and even identity theft. To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins without delay.

applecomsupport.comvpnshieldplus4.com, and safebrowsing.network are examples of other deceptive web pages using an identical scam model as maztek[.]xyz. Other common features include warnings that an essential piece of software is outdated/missing, visitors have won 'amazing' prizes or received similarly unlikely offers, and so on. The purpose of these schemes is to trick people into downloading, installing, purchasing nonfunctional, untrustworthy or malicious content, calling expensive bogus tech support lines, making monetary transactions (e.g. paying fees, fines, etc.) or otherwise encouraging them to inadvertently generate revenue for the scam's designers.

How did potentially unwanted applications install on my computer?

Some PUAs have "official" download sites, which are frequently promoted by deceptive/scam pages. PUAs also proliferate via the download/install set-ups of other software. "Bundling" is the term used to define this deceptive marketing technique of pre-packing normal products with unwanted or malicious apps. Rushing download/installation processes (e.g. skimming or ignoring terms, skipping steps, using presets, etc.) endangers devices with potential infiltration and infections. When an intrusive ad is clicked, it can execute scripts to download/install PUAs without users' consent.

How to avoid installation of potentially unwanted applications

All products should be researched to verify their legitimacy, prior to download/installation. Use official and verified download channels. Avoid free file-hosting websites, P2P sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders - they are untrusted and can offer likewise dubious, even malicious content. When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, functions and other additions. Intrusive advertisements may seem legitimate and harmless, however, they can redirect to dubious sites (e.g. pornography, gambling, adult-dating and so on). If you encounter these ads/redirects, inspect the device and immediately remove all suspect applications and/or browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
