How to remove apps that open the Windows Error Code: WIN.DLL0151930 scam

What is Windows Error Code: WIN.DLL0151930?

Technical support scam websites such as this one often trick unsuspecting visitors into believing that their computers are infected with a virus or multiple viruses (or that some other problem exists) and into calling the provided number.

Once contacted, scammers behind such web pages attempt to trick callers into paying for unnecessary software and services, or providing remote access to their computers. Therefore, this and other similar websites should be ignored.

Like most tech support scam websites, this one is disguised as part of the official Microsoft website. It displays notifications stating that it has detected a virus that can harm data stored on a computer and be used to track financial activities. It also informs visitors that their computers are blocked.

To make this seem authentic, the web page continually downloads various files to render the browser unresponsive. The main purpose of this web page is to deceive users into believing that they will suffer monetary loss, lose data, or have other problems, unless the call the provided number for technical support.

As mentioned, when scammers behind such pages are contacted, they attempt to trick callers into paying for unnecessary software and services. They could demand permission to access computers remotely.

When scammers receive such permission, they attempt to steal sensitive information, which could be misused for malicious purposes (e.g., to make fraudulent purchases and transactions), or they install rogue software onto the operating system (e.g., ransomware, Trojans).

Therefore, you are strongly advised to ignore these tech support scam websites. If they cannot be closed normally, close the entire browser by ending its process via Task Manager. Note that recently closed tabs should not be reopened when the browser is reopened.

There are many technical support scams on the web. Some examples are "MS-Windows Support Alert", "Important Security Alert!" and "TROJAN Error Code 0xdc2dgewc".

Generally, users do not visit these pages intentionally - in most cases, they are opened when users click deceptive advertisements, visit other untrusted pages, or have potentially unwanted applications (PUAs) installed on their browsers.

How did potentially unwanted applications install on my computer?

Unwanted downloads and installations often occur when developers distribute PUAs by integrating them into the download/installation setups of other programs as "extra offers". This distribution method is known as "bundling". The offers can be declined in "Custom", "Advanced" and other similar settings of the setups (or by unticking certain checkboxes).

Many users fail to check and change these settings (or untick the checkboxes), thereby allowing PUAs to infiltrate together with the desired software. PUAs are also downloaded and installed by clicking deceptive advertisements (usually on untrusted sites) that execute certain scripts.

How to avoid installation of potentially unwanted applications

You are advised to research all software before download/installation. Use only official and verified download channels. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, Gnutella, eMule), and other third party downloaders commonly offer harmful and bundled content, and are therefore untrusted and should be avoided.

When downloading/installing, read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features, and so on. Intrusive advertisements typically seem legitimate, however, they can redirect to dubious and malicious sites (e.g. gambling, pornography, adult-dating, and many others).

If you encounter ads or redirects of this kind, inspect the system and remove all dubious applications and browser extensions/plug-ins immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
