How to uninstall apps promoting landoseseq.com and similar sites

What is landoseseq[.]com?

landoseseq[.]com is a deceptive website designed to scare visitors into downloading and installing a potentially unwanted application (PUA). Like most websites of this type, landoseseq[.]com claims to be an official Apple website and to have detected a Trojan on the device.

Notifications, virus alerts and other messages on websites such as landoseseq[.]com are fake and should be ignored. Typically, these web pages are promoted through other untrusted pages, deceptive advertisements, and PUAs.

landoseseq[.]com displays a fake system notification stating that the iPhone has been compromised. It also displays a fake message stating that the device is infected with a Trojan, and accounts, photos, and payment data will become available unless the Trojan is removed immediately.

The main purpose of this page is to trick visitors into downloading and installing a specific application that will supposedly 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. Sometimes, these sites advertise legitimate apps, however, applications should be downloaded only from official pages and App Store.

If a browser opens landoseseq[.]com or other untrusted pages regularly, it is likely that the device has a PUA installed.

These PUAs often serve advertisements and gather data. In most cases, PUAs display coupons, banners, surveys, and pop-up ads. More importantly, the ads tend to be used to advertise untrusted websites or distribute (download/install) unwanted apps by running certain scripts.

PUAs usually gather details such as IP addresses, geolocations, addresses of visited websites, entered search queries, and other browsing data. Some apps of this type can access sensitive information, which developers sell to third parties (potentially cyber criminals) and 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 the device, however, they could also display fake system error notifications. All messages/notifications on these sites are fake.

Note that these apps are 'potentially unwanted' because most users download and install them unintentionally.

How did potentially unwanted applications install on my computer?

People often download and install unwanted apps inadvertently via deceptive advertisements - they click ads that cause unwanted downloads/installations by executing certain scripts.

Unwanted downloads and installations also occur during download/installation of other programs. I.e., when PUAs are included into the set-ups as 'extra offers'. This PUA distribution method of PUAs is called "bundling".

Typically, offers to download and install these additional apps can be declined via "Custom", "Advanced" or other settings, or by unticking certain checkboxes within the set-ups. When users download and install programs without making these checks and changes, they often allow PUAs to infiltrate.

How to avoid installation of potentially unwanted applications

You are advised to download files and programs from official websites and via direct download links. Other tools and sources such as third party downloaders and installers, unofficial pages, and Peer-to-Peer networks (e.g., eMule, torrent clients) should not be used to download or install software.

Check all "Custom", "Advanced" and other similar settings (or available checkboxes) for offers to download and/or install unwanted apps. Do not click ads on dubious websites, since they can be designed to open bogus web pages or cause unwanted downloads and installations.

Remove any unwanted, suspicious extensions, plug-ins and add-ons installed on the browser, and software of this kind from 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.
