How to remove apps that promote securitycheck[.]network from Mac?
What is securitycheck[.]network?
Securitycheck[.]network is a fake Apple website which is designed to trick visitors into downloading and installing some application. It is not common for pages like securitycheck[.]network to be visited by users intentionally. In most cases such pages are promoted via deceptive ads, other shady pages or potentially unwanted applications (PUAs).
Securitycheck[.]network displays a fake virus notification saying that iPhone has been infected with 4 viruses that should be removed immediately, otherwise they will block the phone, SIM card and corrupt data. It encourages to remove those viruses with some app called "My Security" that can be downloaded via the provided "remove viruses" link. Applications should never be downloaded from or through pages like securitycheck[.]network. If such pages get opened often, it is likely that they get opened by some installed PUA.
PUAs can be designed not only to promote untrustworthy pages but also to generate ads and gather various information. It is common that PUAs target IP addresses, websites of visited pages, entered search queries, geolocations, etc. Although, some of them could capable of accessing sensitive details as well. Moreover, collected data could be monetized by selling it to third parties (potentially cyber criminals) or misused in other ways. Also, PUAs can be deigned to generate coupons, banners, surveys, pop-ups and other ads. Quite often their ads are designed to open untrustworthy websites, or even cause unwanted downloads, or even installations of unwanted apps.

Examples of pages that are similar to securitycheck[.]network are department[.]limited, spaceshellvpn[.]com, peachlandeu[.]com. What most of them have in common is that they claim that visitor's device is infected and encourage to install some app that supposed to remove threats. In one way or another, neither securitycheck[.]network or any other page of this kind can be trusted.
How did potentially unwanted applications install on my computer?
Most users download and/or install potentially unwanted apps unknowingly. It is common that they download and/or install them together with programs. More precisely, when they do not decline unwanted offers when they download and/or install programs that have PUAs included in their setups. Usually such offers can be declined via "Custom", "Advanced", or other settings or by unticking certain checkboxes before finishing downloads and/or installations. This distribution method for PUAs is known as "bundling". Sometimes users cause unwanted downloads, installations by clicking deceptive advertisements that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
Download and installation setups that have settings like "Custom", "Advanced", or some checkboxes, should be always checked for offers to download and/or install unwanted apps. Software (and files) should be downloaded from official pages and through direct links. Other channels, sources like third party downloaders, unofficial web pages, Peer-to-Peer networks (e.g., torrent clients, eMule) should not be used, neither should be various third party installers. Also, it is advisable not to click ads that appear on dubious pages. Quite often those ads are designed to open various questionable websites or cause unwanted downloads, installations. Additionally, there should not be any unwanted extensions, plug-ins or add-ons that are installed on a browser, or programs of this kind that 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.
