How to remove apps that promote system-protection-required[.]com?

What is system-protection-required[.]com?

Typically, pages like system-protection-required[.]com display fake notifications suggesting that a device may be not safe or it is already infected with some viruses, or other threats and encourage visitors to download and install some application that supposedly will remove viruses, protect the device, etc. Most of the times users end up on pages like system-protection-required[.]com after visiting other shady pages, clicking deceptive ads, or when they have some potentially unwanted application (PUA) installed on a device (or a browser). In other words, it is very uncommon for pages like system-protection-required[.]com to be visited by users intentionally.

system-protection-required[.]com scam

System-protection-required[.]com displays different fake notifications saying that the iPad or iPhone may be hacked, personal information may be stolen, Apple ID may be blocked, iPhone is severely damaged by 19 viruses/browser is infected with Trojan viruses and they need to be removed as soon as possible, otherwise Facebook, WhatsApp accounts, photos, and private applications will be infected and stolen. A couple of system-protection-required[.]com variants display notifications suggesting to install a security app to watch videos in safe mode. It is known that one of the system-protection-required[.]com variants promotes an application called AdsBlock for Safari. It is noteworthy that even when pages like system-protection-required[.]com promote legitimate applications, it does not make them any more trustworthy. Besides, it is possible that such pages could be used to promote browser hijackers, adware, or other PUAs. Applications should be downloaded only from legitimate sources, e.g., from official pages or App Store.

If pages like system-protection-required[.]com get opened regularly, then it is very likely that there is PUA installed on a device or a browser. In such case that application should be removed, it could be designed to gather various information, or generate ads as well. It could be gathering browsing data like IP addresses, geolocations, addresses of visited pages, entered search queries, or even personal, sensitive data that may be sold to third parties (potentially cybercriminals), or misuses to generate revenue in other ways. Also, a PUAs could be designed to generate banners, pop-up ads, surveys, coupons or other ads that, if clicked, would open potentially malicious sites or cause unwanted downloads, installations. Either way, browser and the operating system should no have any unwanted app installed on it.

More examples of websites like system-protection-required[.]com are peachsecureus[.]com, reander[.]net and systemnotices[.]com. What all of them have in common is that they say that there is or may be some problem with a device and encourages to solve it by installing one or another application. In conclusion, websites of this type are designed to advertise software using deceptive techniques. None of these websites are trustworthy and should never be used as sources for downloading any software/applications.

How did potentially unwanted applications install on my computer?

In most cases users unintentionally download or install unwanted applications when they download or install other programs that are bundled together with those unwanted apps. Usually, users can choose whether to allow included apps to be downloaded, installed, or not. Unwanted offers can be declined using "Advanced", "Custom", "Manual" or other settings, or by unticking checkboxes that many downloaders, installers have. When users download or install programs without checking and changing any setting, they download or install the offered (bundled) apps too. In some cases users cause unwanted downloads, installations by clicking deceptive advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Downloaders and installers that have "Advanced", "Custom" and other similar settings, or some checkboxes should be always checked for unwanted offers. Downloads and installations should be finished only when all unwanted offers are declined. Applications and files should be downloaded from official pages and via direct links. Other sources like third party downloaders, torrent clients, eMule (and other Peer-to-Peer networks), unofficial pages, etc., are not trustworthy. The same applies to third party installers. Advertisements that get displayed on questionable websites tend to be designed to open untrustworthy websites or even download, install unwanted software. Therefore, such ads should not be clicked as well. There should not be any unwanted, suspicious extensions, plug-ins or add-ons installed on a browser, neither there should be any apps 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.
