How to remove software force-opening the check-this-message.one site?

What is check-this-message[.]one?

Check-this-message[.]one is a rogue site designed to load dubious material and/or redirect visitors to other untrustworthy and malicious webpages. The Internet is rife with such websites; brokenbad.biz, sweetadvance.ru, watch-this-viral.video, antom.xyz - are just some examples.

Users seldom intentionally access rogue pages. Most get redirected to them by suspect sites, intrusive advertisements, or installed PUAs (Potentially Unwanted Applications). These apps can be installed onto devices without explicit permission and force-open webpages, run intrusive ad campaigns, and collect browsing data.

Check-this-message[.]one in detail

The behavior of check-this-message[.]one is dictated by the visitor's geolocation. The website learns this information by checking the visiting user's IP (Internet Protocol) address. Therefore, whether visitors get redirected elsewhere and/or are presented with questionable content - depends on their geolocations.

Furthermore, most rogue sites employ deceptive tactics to trick users into enabling their browser notifications. Check-this-message[.]one is not an exception to this; should its notifications be allowed - the webpage will start running intrusive advertisement campaigns.

The delivered adverts are more than just a minor annoyance, they also pose a threat to device/user safety. These advertisements endorse a wide variety of untrustworthy and malicious websites. What is more, some intrusive ads can stealthily download/install software (e.g., PUAs).

How do potentially unwanted applications operate?

Potentially unwanted applications can have different functionalities, and these functions can be in varied combinations. For example, this software can cause redirects and/or deliver intrusive advertisement campaigns. PUAs usually have data tracking abilities.

Information of interest includes (but is not limited to): URLs visited, webpages viewed, search queries typed, IP addresses/ geolocations, and personally identifiable details. The gathered data is then shared with and/or sold to third-parties (potentially, cyber criminals).

In summary, the presence of unwanted apps on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft. To ensure device integrity and user privacy, all suspect applications and browser extensions/plug-ins must be eliminated immediately upon detection.

Potentially unwanted applications in general

PUAs appear ordinary and harmless. These applications also offer "handy" features, which are seldom operational. The only goal of unwanted software is to generate revenue for the developers; hence, functionality and user safety are irrelevant. PUAs are designed to force-open pages, run intrusive ad campaigns, and gather private data.

How did adware install on my computer?

PUAs are distributed via download/installation setups of other programs. This false marketing tactic of packing regular software with unwanted or malicious additions - is termed "bundling". Rushed downloads/installations (e.g., skipped steps, used pre-set options, etc.) increase the risk of allowing bundled content into the system.

Intrusive advertisements are used to spread PUAs as well. Once clicked on, the ads can execute scripts to download/install these applications without user consent. Some PUAs may also have "official" promotional sites from which they can be downloaded and/or purchased.

How to avoid installation of potentially unwanted applications?

It is recommended to research software before download/installation. Additionally, all downloads must be performed from official and verified sources. Untrustworthy download channels, e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders - often offer bundled and harmful content.

When downloading/installing, it is advised to read terms, study available options, use the "Custom/Advanced" settings to opt-out from additional apps, tools, functions, etc. Intrusive adverts appear legitimate; however, they redirect to various questionable sites (e.g., pornography, adult-dating, gambling, and so on).

In case of encounters with ads and/or redirects of this kind, the system must be checked and all suspicious applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

Only allow notifications from websites that you fully trust. For added security - use an anti-malware application with a real-time web browsing monitor to block shady websites that tries to trick you into allowing spam notifications. We recommend using Combo Cleaner Antivirus for Windows.
