What is WARNING CRITICAL MESSAGE?
There are many technical support scam websites pretending to be official Microsoft (or other company) websites and claiming that a computer is blocked, infected or there is some other problem that needs to be solved as soon as possible. It is common that such pages display some pop-up window (or multiple windows) instructing the potential victim to call the provided number for technical support. Once contacted, scammers usually instruct users to download and install some remote access software/give them a remote access to a computer, or pay money for some unnecessary software, or technical services.
This particular technical support scam website displays a fake error, warning messages saying that Windows has been blocked due to suspicious activity and data like passwords, browsing history, sensitive information like credit card details, and files on the hard drive may be stolen. The main purpose of this website is to trick visitors into believing that they need to call the +1-888-357-5053 number to prevent further damage. It is likely that scammers behind this page would ask to give them remote access to a computer, sell unnecessary software or repair services, ask for personal information (like credit card details). It is important to know that by having a remote access to a computer scammers could access all information stored on it, or even install some malware on it (e.g., ransomware, Trojan-type malware, cryptomining malware).

As mentioned in the first paragraph, there are many various technical support scam websites, some more examples are "ERROR #DW6BD36", "Error # WINDOWS-PORN-91" and "Killer's IP Address". Regardless of the tactics that scammers behind such pages use, they have one purpose - to make money. Typically, users do not visit such pages intentionally. One of the reasons why such pages get opened by a browser is because there is some potentially unwanted application (PUA) installed on it (or the operating system).
How did potentially unwanted applications install on my computer?
In most cases users download and/or install potentially unwanted applications unknowingly - when developers distribute them by using a "bundling" method. More precisely, when PUAs distributed by including them in download and/or installation setups of other programs as extra offers. As a rule, unwanted offers can be declined via "Custom", "Advanced", or other settings, or by unticking certian checkboxes before finishing downloads and/or installations. Although, quite often users download and/or install programs without checking and changing the aforementioned settings. In some cases users cause unwanted downloads and/or installations via deceptive advertisements - by clicking ads that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
Programs and files should not be downloaded from shady, unofficial pages, via Peer-to-Peer networks (e.g., torrent clients, eMule), third party downloaders, and so on, or installed with third party installers. That should be done by using official websites and direct links. Furthermore, downloads and installations should not be finished without declining offers to download and/or install additionally included, unwanted apps. Ads on questionable web pages should not be trusted (clicked) as well. It is common that those ads open other websites of this kind or even cause unwanted downloads, installations. Unwanted extensions, plug-ins or add-ons that are installed on a browser and programs of this kind that are installed the operating system should be uninstalled. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
