"VIRUS ALERT FROM Windows" removal instructions
What is "VIRUS ALERT FROM Windows"?
Like many other technical support scams, this one is designed by scammers who attempt to trick unsuspecting users into calling them via the provided number. In most cases, their main purpose is to trick people into paying to fix a non-existent computer problem (remove viruses). In any case, such scams should be ignored. Note that the deceptive websites associated with these scams are often opened through dubious ads, bogus websites, or installed potentially unwanted applications (PUAs).
This technical support scam website displays a pop-up window/deceptive notification claiming that the user's computer (Windows registration key) is blocked due to some installed software being pirated, the Windows registration key is illegal, and the operating system is hacked and/or used from an undefined location and is sending viruses over the internet. To unblock the computer and prevent possible tracking of data and financial activities, the user is encouraged to call the +1-844-900-0923 number, supposedly a Microsoft Support (helpline) number. Generally, scammers behind these websites try to sell fake technical support software or services. The scammers commonly ask users to install software that gives them remote access to the computer. Scammers can then steal sensitive information and install malicious software (e.g., ransomware, Trojans). In any case, you are strongly advised not to trust these scams and simply ignore them. Scam pages that prevent users from closing them can be forcibly closed through Task Manager by terminating (ending) the running browser process.
As mentioned, technical support scams and other deceptive web pages are often opened by browsers with PUAs installed on them. These apps not only promote untrusted websites, but also gather various data and display ads. Typically, they collect browsing data such as IP addresses, entered search queries, addresses of visited pages, geolocations, and other data of this kind. They might also record personal, sensitive details as well. Furthermore, the developers can sell the information to third parties (potentially, cyber criminals) or misuse it to generate revenue in other ways. Collected data is often misused to steal identities, or for other purposes. Therefore, users might become victims of identity theft, experience problems relating to browsing safety, online privacy, etc. The apps can also display coupons, banners, surveys, coupons and other ads. These open dubious web pages and, in some cases, execute scripts designed to download and install PUAs or other unwanted software. Therefore, you should remove all PUAs from browsers and computers immediately.

Some more examples of similar scams are "Windows Firewall Has Blocked Some Features Of This Program", "Error # 0x80092ee9" and "System Warning Alert". The scammers behind them generate revenue by offering paid fake technical support. In some cases, the criminals try to trick people into giving them remote access to computers. By trusting these scams, users can suffer monetary loss, become victims of identity theft, have their computers infected with malware, and experience other issues. If such web pages are opened often, it is very likely that the browser has PUAs installed.
How did potentially unwanted applications install on my computer?
Typically, potentially unwanted applications are distributed by including them into the download/installation set-ups of other programs. This distribution method is known as "bundling". PUAs are included as 'additional offers' and are generally listed in "Custom", "Advanced" or other settings. When users download and install their programs without checking and changing the aforementioned settings, they agree by default with offers to download and install additionally-included apps. In some cases, unwanted downloads and installations are caused through deceptive advertisements that, when clicked, execute certain scripts.
How to avoid installation of potentially unwanted applications
Do not use dubious websites, Peer-to-Peer networks (torrent clients, eMule), third party downloaders, installers or other similar methods to download or install programs/files. Software and files should be downloaded only from official websites and through direct download links. Check all "Custom", "Advanced" and other settings, and decline offers to download or install PUAs before completing the process. Do not click intrusive ads, especially if they appear on dubious web pages. These might be capable of running scripts to download and install unwanted apps. Remove any unwanted, suspicious apps (extensions, plug-ins, add-ons) already installed on the browser immediately. The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
