Check-this[.]news redirect removal instructions

What is check-this[.]news?

Check-this[.]news is more or less similar to chat-message[.]live, tlouslyrevor[.]top, yskimmed[.]top and many other rogue pages. Typically, pages like check-this[.]news are promoted via other shady websites, deceptive advertisements and/or by potentially unwanted applications (PUAs). In other words, it is not common for users to open/visit such pages intentionally.

check-this[.]news pop-up redirects

Once websites like check-this[.]news get visited, they either open other (about 2-3) shady pages or load dubious content. What happens next depends on the geolocation of their visitors. Another issue with pages like check-this[.]news is that most of t them are designed to deceive visitors to giving them permission to show notifications by using a clickbait technique. Check-this[.]news suggests that to continue loading it visitors need to allow it to show notifications (to click the "Allow" button). As a rule, notifications from websites like this one contain various deceptive ads, links to shady pages, etc.

As mentioned in the first paragraph, it is common that websites like check-this[.]news are promoted via PUAs. It is worthwhile to mention that such apps can be designed to collect various data. For example, IP addresses, entered search queries, geolocations, addresses of visited websites, and other browsing-related details, or even personal, sensitive data. That data could be monetized by selling it third parties (potentially cyber criminals), or in other ways. In such cases users of PUAs may encounter problems related to privacy, browsing safety, or even become victims of identity theft. Also, PUAs can be designed to generate ads (e.g., coupons, pop-ups, surveys, banners) that, if clicked, would open potentially malicious pages or download and/or install unwanted apps by running certain scripts.

One more detail about most PUAs is that they do not improve browsing experience, include any features or are useful to their users in some other way. Even when they are advertised as useful, legitimate applications. The main reason why they are called potentially unwanted is because it is not common for them to be downloaded and installed by users intentionally.

How did adware install on my computer?

Quite often potentially unwanted applications are distributed by including them in download and/or installation setups of other programs as extra offers. This distribution method is known as "bundling". Typically, users can decline offers to download and/or install via "Custom", "Advanced", or other settings, or by unticking certain checkboxes. When users download and/or install programs without checking and changing any of those settings, they download and/or install offered apps as well. Also, in some cases unwanted downloads and/or installations caused by users when they click deceptive ads that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Programs and files should not be downloaded from unofficial websites, via Peer-to-Peer networks (torrent clients, eMule, and so on), third party downloaders, and so on, or installed via third party installers. It should be done by using official websites and direct links. Downloads and installations should not be finished without checking if download and/or installation setups have "Custom", "Advanced", or other settings that could be used to decline unwanted offers. Ads on shady pages can be designed to open questionable websites or cause unwanted downloads, installations. Therefore, such ads should not be clicked as well. Unwanted extensions, plug-ins or add-ons that are installed on a browser and programs of this kind that are installed on the operating system should be uninstalled. If your computer is already infected with rogue applications, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
