How to remove apps that open extrasafe[.]xyz (and similar sites) from Mac computers

What is extrasafe[.]xyz?

extrasafe[.]xyz is a deceptive website, the main purpose of which is to trick visitors into downloading and installing a potentially unwanted application (PUA). The app is apparently capable of removing viruses that this website has supposedly detected. Commonly, pages such as extrasafe[.]xyz are opened through other websites of this kind, clicked deceptive advertisements, and installed PUAs. In any case, people do not often visit these sites intentionally. Do not trust these sites or download applications from them - use only official websites.

extrasafe[.]xyz scam

There are at least two versions of the extrasafe[.]xyz site (mobile and desktop) - one suggesting that the visitor's device is infected with viruses,  the other suggesting that it might be tracked. The main goal is to deceive visitors into installing an application (at the time of research, extrasafe[.]xyz promoted apps named Globe VPN-Internet Security and Fireblocker Security - Adblock), which supposedly remove viruses and/or prevent further damage. Neither extrasafe[.]xyz nor other similar deceptive pages can be trusted, even if the advertised apps are legitimate. All software should be downloaded from official web pages, and never through or from sites such as this one. As mentioned, browsers generally open these sites due to installed PUAs.

Note that promotion of dubious, deceptive websites is not the only problem with the aforementioned PUAs. They often serve ads and collect browsing-related data. They feed users with various ads. For example, coupons, banners, surveys, and pop-ups. When clicked, these can open untrusted websites or even execute scripts designed to cause download/installation of unwanted apps. PUAs can also record details such as addresses of visited websites, entered search queries, geolocations, IP addresses and other browsing data. They sometimes access and record personal details as well. Furthermore, developers misuse the data to generate revenue by selling it to third parties (potentially, cyber criminals) or in other ways. PUAs can cause thus problems such as identity theft, issues relating to browsing safety, online privacy, and other issues. Therefore, all PUAs should be uninstalled immediately and avoided in future.

Some more examples of deceptive web pages are berrigroun[.]com, application-update[.]com and hastopnet[.]com. Typically, they suggest that the visitor's device is infected with viruses, is exposed to problems relating to privacy, browsing safety, etc., and encourages the user to solve the supposed problem with a specific application. Generally, people download and install PUAs inadvertently, and this is often the reason why browsers open dubious web pages.

How did potentially unwanted applications install on my computer?

In most cases, people are tricked into downloading and installing potentially unwanted apps when developers distribute them using a deceptive marketing method called "bundling". This method is used to trick people by including the unwanted applications into the set-ups of other programs as 'additional offers'. Generally, information about additionally-included apps can be found in "Advanced", "Custom and other similar settings, however, many users leave the settings unchecked and unchanged, thereby allowing PUAs to infiltrate. In some cases rogue downloads/installations happen through clicking deceptive advertisements, which then execute certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to download all software from official and trustworthy websites. Avoid third party downloaders, installers, unofficial web pages, Peer-to-Peer networks (torrent clients, eMule) and other channels of this kind. Check all "Custom", "Advanced" and other settings available in the setup and decline offers to download or install additionally-included apps. Do not click ads that appear on dubious web pages (e.g, adult dating, gambling, pornography pages), since they can open untrusted websites or even cause download/installation of unwanted, potentially malicious apps. Remove any, suspicious extensions, plug-ins, and add-ons installed on the browser, and programs of this kind installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
