How to remove apps downloaded from landoseseq[.]com?
What is landoseseq[.]com?
Landoseseq[.]com is a deceptive website designed to scare its visitors into downloading and installing a potentially unwanted application (PUA). Like most websites of this type, landoseseq[.]com pretends to be an official Apple website and claims to have detected a Trojan on a device. Notifications, virus alerts, or other messages on websites like landoseseq[.]com are fake and should be ignored. Typically, pages like landoseseq[.]com are promoted through other untrustworthy pages, deceptive advertisements, or potentially unwanted apps.
Landoseseq[.]com displays a fake system notification saying that the iPhone has been compromised. Also, it displays a fake message saying that a device is infected with a Trojan, and accounts, photos, and payment data will become available if that Trojan is not removed immediately. The main purpose of this page is to trick visitors into downloading and installing a certain application that is supposed to remove the "detected" Trojan and prevent it from causing further damage. Deceptive websites like landoseseq[.]com can be used to advertise browser hijackers, adware (and other PUAs), or even malicious apps. Although, sometimes, these sites advertise legitimate apps. In one way or another, applications should be downloaded only from official pages, App Store. If a browser opens landoseseq[.]com and other untrustworthy pages regularly, then it is likely that a device has a PUA installed on it.
It is common that PUAs serve advertisements and (or) gather data as well. In most cases, PUAs display coupons, banners, surveys, pop-up ads. More importantly, those ads tend to be used to advertise untrustworthy websites or distribute (download or install) unwanted apps by running certain scripts. PUAs usually gather details like IP addresses, geolocations, addresses of visited websites, entered search queries (and other browsing data). Although, there are apps of this kind that can access sensitive information. What is worse, there is always a possibility that their developers would sell gathered information to third parties (potentially cybercriminals), use it for marketing (or other) purposes.

More examples of pages using scare tactics to trick users into installing potentially unwanted software are security-protect[.]systems, penit[.]xyz, and alert-info[.]space. Usually, these pages claim to have detected malware on a device. Although, they could display fake system error notifications as well. In one way or another, messages/notifications on these sites are never real. It is worthwhile to mention that PUAs are called potentially unwanted because most users download and install them unknowingly, unintentionally.
How did potentially unwanted applications install on my computer?
Quite often, users download and install potentially unwanted applications together with other programs. When PUAs are bundled in downloaders, installers for those programs. In such cases, downloaders or installers have settings "Manual", "Custom", "Advanced" (or other settings), or some checkboxes. Users agree to download or install bundled apps when they do not change those settings or untick checkboxes before finishing downloads or installations. Sometimes users unintentionally cause unwanted downloads or installations by clicking deceptive advertisements. More precisely, by clicking advertisements designed to run certain scripts. Typically, such ads appear on questionable, untrustworthy web pages.
How to avoid installation of potentially unwanted applications?
Applications should never be downloaded (or installed) via third-party downloaders (or installers), Peer-to-Peer networks like eMule, torrent clients, unofficial sites, etc. It is recommended to use only official websites and platforms such as App Store. Downloaders and installers that have "Custom", "Advanced" and other similar settings or checkboxes should be checked for bundled applications. It is important to decline unwanted offers before finishing downloads, installations. Ads on shady pages should not be clicked as well - most of those ads advertise untrustworthy sites. Sometimes they can be designed to download, install unwanted apps. Unwanted extensions, plug-ins or add-ons installed on a browser and apps of this kind installed on the operating system should be removed as soon as possible. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
