What is Windows Error Code: WIN.DLL0151930?
Technical support scam websites like this one are designed to trick unsuspecting visitors into believing that their computers are infected with a virus or multiple viruses (or there is some other problem) and calling the provided number. Once contacted, scammers behind such pages attempt to trick callers into paying money for unnecessary software, services or providing a remote access to their computers. Therefore, this or any other similar website should be ignored.
Like most tech support scam websites, this one is disguised as one of the official Microsoft websites. It displays notifications saying that it has detected a virus that may harm data stored on a computer and used to track financial activities. Also, it informs visitors that their computers are blocked and to make it look like it is true this page constantly downloads various files to make a web browser unresponsive. The main purpose of this page is to deceive users into believing that they will suffer monetary loss, lose data and/or have some other problems if they will not call the provided number for technical support. As mentioned in the introduction, when scammers behind such pages are contacted, they attempt to trick callers into paying money for unnecessary software and/or services. Also, they could ask for a permission to access computers remotely. When scammers get such permission they attempt to steal sensitive information that could be misused for malicious purpose (e.g., make fraudulent purchases, transactions) or install some malicious software on the operating system (e.g., ransomware, Trojans). Therefore, it is strongly recommended to ignore tech support scam websites. If they cannot be closed normally, then it is advised to close the whole browser by ending its process via Task Manager. It is worthwhile to mention that recently closed tabs should not be reopened when a browser is opened the next time.

There is a great number of technical support scams, some examples are "MS-Windows Support Alert", "Important Security Alert!" and "TROJAN Error Code 0xdc2dgewc". As a rule, users do not visit such pages intentionally. In most cases they get opened when users click deceptive advertisements, visit other untrustworthy pages of have some potentially unwanted application (PUA) installed on their browser.
How did potentially unwanted applications install on my computer?
In some cases users download and/or install PUAs by clicking deceptive advertisements that are designed to cause it by executing certain scripts. However, in most cases they get tricked into it when developers distribute PUAs by using a deceptive marketing method called "bundling". To be more precise, when they include PUAs in download and/or installation setups of other programs as additional offers. In most cases those offers can be found and declined in "Custom", "Advanced" and other similar settings of setups (or via certain checkboxes). Users who download and install programs without checking and changing those default settings allow for included PUAs to be downloaded and/or installed as well.
How to avoid installation of potentially unwanted applications?
It is recommended to always check "Advanced", "Custom" and other settings of any download and installation setup and see if they can be used to decline offers to download and/or install unwanted apps. Also, it is important to download software from official, trustworthy sources (websites) and not to use third party downloaders, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites and other similar channels/tools for that. Third party installers should not be used too. Ads that appear on shady pages, if clicked, could open other untrustworthy sites, or even run scripts that would download and/or install some unwanted software. Therefore, such ads should bot be clicked as well. Any unwanted apps (extensions, add-ons or plug-ins) that are already installed on a browser should be removed. Software of this kind that is installed on the operating system should be uninstalled too. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
